28 Energy Engineering Questions and Answers:
Table of Contents:
8 :: A 3.3 k resistor dissipates 0.25 W. The current is
A. 8.7 mA
B. 87 mA
C. 8.7 µA
D. 8.7 A
Option A
Explanation:
W = I2R
I = square root(W/R)
= square root( 0.25/(3.3x1000) )
= 0.0087038828
= 8.7 mA
Explanation:
W = I2R
I = square root(W/R)
= square root( 0.25/(3.3x1000) )
= 0.0087038828
= 8.7 mA
