8. A voltmeter measures a voltage drop of 600 V across a heating element while an
ammeter reads the current through it as 2.0 A. What is the resistance of the
heating coil.
Answer:
How do I calculate voltage drop?
To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm's Law is E=I⋅R , which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop

1. Explain the difference between energy and power (2)
Explanation:
Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred. It is not energy but is often confused with energy.
Answer:
• Energy is the ability to do work, and it can be transferred from one body (or system) to another, but is always conserved.
• Power is the amount of energy transferred per unit time.

A cutting tool wears out with a time to failure that is normally distributed with a mean of 10 working days and a standard deviation of 2.5 days. (a) determine its design life for a reliability of 0.99. (b) find the reliability if the tool is replaced every day; every two days; every five days. (c) determine the probability that the cutting tool will last one more day given it has been in use for 5 days.
Using the normalized distribution it is possible to calculate the value of Z score and for cases where there is a 99% chance, so Zscore is -3.6 and X= 16.45.
What are the types of probability distribution?This curve determines the probability of the event associated with it occurring. The Gaussian distribution is the most common, hence it is known as the Normal Distribution. The area under the distribution curve is always equal to 1.0.
The formula for this distribution can be described as:
[tex]Z score = \frac{x-\mu}{\sigma}[/tex]
Where:
x= Probability density functionμ= Meanσ= Standard DeviationIn this case,
[tex]Z score =\frac{1-10}{2.5} \\Z score = -3.6[/tex]
P-value from Z-Table will be P(x<1) = 0.00015911
For 99% we have that z will be 2.58, so
[tex]2.58=\frac{x-10}{2.5}\\x = 16.45[/tex]

If a 1500 V load is ac coupled to the output in Figure 9–60, what is the resulting output voltage (rms) when a 50 mV rms input is applied? gm = 5000 mS.
The resulting output voltage (rms) when a 50 mV rms input applied is -187.5 mV.
What is rms voltage?Root Mean Square Voltage is the amount of AC power which produces the same heating effect as DC Power would have produced.
Vo = -gm x Vi (Rd II Rl )
Vo = -5000 x 10⁻⁶ x 50 x 10⁻³ x (1.5k II 1.5k )
Vo = -25 x 10⁻² x 750 x 10⁻³
Vo = -187.5 mV
Hence, resulting output voltage (rms) when a 50 mV rms input applied is -187.5 mV.
