Part 1: Answer the following questions (20 points)
1. Name and describe the components needed to make a complete circuit.
2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.
3. Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.
4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same.
Part 2: Design your own circuit (40 points)
Design a circuit and draw a circuit diagram using the proper symbols. Your circuit must contain a battery, a light bulb (if you would like to substitute another item that uses electrical power you may), a switch, an ammeter, and a resistor. After you draw your circuit, complete the questions which ask you to describe the circuit that you have created. You may hand draw the circuit and scan or fax the worksheet to submit for grading. Or you may use a draw/paint program to create your circuit in the space provided.
Circuit Diagram:
Question 1: Is the circuit you created a parallel, series or a series/parallel circuit? Support your answer with a description of this type of circuit.
Question 2: What is the purpose of the resistor in your circuit?
Question 3: How does the switch work?
Question 4: Describe the path of the electric current through your circuit.
Question 5: Explain how your battery works. (You may want to look at the Electric Current lesson) What are some possible materials you could use to make your battery?
Answers
Answer: part 1
1. You need a Source of electric power (battery or generator), a load to absorb the power (lamp, motor, heating coil) and wiring to connect the load to the power source!
2. they both give off electricity energy, and they are different because they dont release the same amount of energy
3. Current will increase
Explanation:
In Ohm's law the equation for current is current = voltage / resistance.
In order to explain how current is effected when resistance decreases while voltage stays the same, lets represents the situations with some possible inputs.
Let's compare 3 different closed circuits all with a voltage of 10V.
In circuit 1, the resistance is 5 ohm.
In circuit 2, the resistance is 2 ohms.
In circuit 3, the resistance is 1 ohms.
The current of:
Circuit 1 = Voltage / Resistance = 10 V / 5 ohms = 2 Amps
Circuit 2 = Voltage / Resistance = 10V / 2 ohms = 5 Amps
Circuit 3 = Voltage / Resistance = 10V / 1ohm = 10 Amps
As you can see in this representation, as the resistance in a circuit increases while the voltage is constant, the total current is increased.
4. The resistance of a conductor is the ratio of the voltage
between its ends to the current through it.
If the voltage between the ends of a light bulb's filament
increases but the filament's resistance remains constant,
then the current through it increases by the same factor
as the voltage increase. The effect is to cause the light
to emit more light and heat ... both increase proportional
to the square of the voltage ... and possibly to "burn out".
Part 2
1. it's a circuit wherein all the elements are in parallel and a resistance is fitted in series across which a voltmeter is connected to measure potential drop acrossR so as to find the current across the load that is bulb which connected to in series with the resistor
2. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
3. The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.
4. the current runs through the motherboard and into the smaller components or the small internal wiring
5. A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.
Typical materials of a battery are as follows
- Anode most often is made of zinc
- Manganese dioxide acting as Cathode.
- the electrolyte between and inside contains ions

A 2 digit number is such that thrice the sum of its digits is less than the value of the number by 8.
When the digits are reversed the number increases by 9.
Find the number.
Answers
Answer:
23
Step-by-step explanation:
Let "ab" represent the digits of the number.
"thrice the sum of its digits is less than the value of the number by 8"
The value of the number is 10a+b.
3(a+b) = (10a+b) - 8
3a+3b = 10a+b-8
7a-2b = 8
"When the digits are reversed the number increases by 9"
Value of "ba" = 10b+a
(10b+a) - (10a+b) = 9
9b-9a = 9
b-a = 1
b = a+1
7a-2(a+1) = 8
5a -2 = 8
a = 2
b = a+1 = 3
"ab" = 23

In a study of 900 adults, 45 out of the 325 men in the study said that they preferred to rent a movie on DVD rather than going out to a movie theater. What is the approximate percentage of men in this study who prefer to rent a movie on DVD
Answers
Answer:
[tex]\%DVD = 14\%[/tex]
Step-by-step explanation:
Given
[tex]Population = 900[/tex]
[tex]Sample = 325[/tex] --- selected adults
[tex]Proportion = 45[/tex] --- those that prefer renting a movie
Required
Represent the proportion as a sample.
This is calculated as thus:
[tex]\%DVD = \frac{Proportion}{Sample} * 100\%[/tex]
[tex]\%DVD = \frac{45}{325} * 100\%[/tex]
[tex]\%DVD = \frac{45 * 100}{325}\%[/tex]
[tex]\%DVD = \frac{45 00}{325}\%[/tex]
[tex]\%DVD = 13.85\%[/tex]
[tex]\%DVD = 14\%[/tex] --- approximated

Find the range of the data set.
Answers
Answer:
37
Step-by-step explanation:
Highest - lowest = range
64-27= 37
The range of the data set is given by the equation R = 37
What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.
Given data ,
Let the data set be represented as Set A
Now , the value of A is
Substituting the values in the equation , we get
A = { 27, 56, 64, 36, 40, 29, 27, 56, 30 }
Arranging the values in set A in the ascending order , we get
A = { 27 , 27 , 29 , 30 , 36 , 40 , 56 , 56 , 64 }
Now , the range of the set = largest value - smallest value
On simplifying the equation , we get
The range R = 64 - 27
The range of set R = 37
Hence , the range is 37
