Question

the current in a resistor is 5.0 a, and its resistance is 60 w. what is the voltage? 12 v 300 v 0.12 v 30 v question 5 (3 points) the correct formula for electric power is v = r×i p = v×i i = v×p p = r×i

Explanation:

Step1: Identify the formula

Use Ohm's law $V = I\times R$, where $V$ is voltage, $I$ is current and $R$ is resistance.

Step2: Substitute values

Given $I = 5.0\ A$ and $R=60\ \Omega$, then $V=5.0\times60$.

Step3: Calculate the result

$V = 300\ V$.

For the second - part:
The formula for electric power is $P = V\times I$, where $P$ is power, $V$ is voltage and $I$ is current.

Answer:

For the first question: B. 300 V
For the second question: B. $P = V\times I$
