$$\text { Figure } 3

Question

$$\text { Figure } 3 < 1$$
-If  V=100 V  and  I=1 mA in Figure  3-1 , the power dissipated by the resistor equals_____
A) 1 W 
B) 10 W 
C) 100 mW 
D) 10 mW

Quizplus · Accepted Answer

Using Ohm's law, we can calculate the resistance of the resistor to be:
R = V/I = 100V/(1mA) = 100 kΩ
Then, using the formula for power (P = IV = I^2R = V^2/R), we can calculate the power dissipated by the resistor:
P = (1mA)^2 * 100 kΩ = 100 µW = 0.1 mW
Therefore, the best choice is C with an answer of 100 mW (closest choice to the calculated value).
