Question

question 1 of 25
a circuit has a voltage drop of 60.0 v across an 80.0 ω resistor that carries a current of 0.750 a. what is the power used by the resistor? use p = vi.
a. 45.0 w
b. 60.0 w
c. 2.00 w
d. 4800.0 w

Explanation:

Step1: Identify given values

$V = 60.0\ V$, $I=0.750\ A$

Step2: Apply power formula

$P = VI$
Substitute $V = 60.0$ and $I = 0.750$ into the formula: $P=60.0\times0.750$
$P = 45.0\ W$

Answer:

A. 45.0 W
