Question

if a load is using 10 amps at 12 volts, how many watts of power is this according to the watts law calculation?
select one:
a. 22 watts
b. 100 watts
c. 120 watts
d. 180 watts

Explanation:

Step1: Recall Watt's Law

Watt's Law states that power \( P \) (in watts) is calculated as the product of voltage \( V \) (in volts) and current \( I \) (in amps), so the formula is \( P = V \times I \).

Step2: Substitute the given values

We are given that the current \( I = 10 \) amps and the voltage \( V = 12 \) volts. Substituting these values into the formula, we get \( P = 12 \times 10 \).

Step3: Calculate the result

\( 12 \times 10 = 120 \) watts. So the power is 120 watts.

Answer:

c. 120 watts
