19. find the current in a circuit if the power is 500 w (watts) and the resistance is 25 ohms. round off your answer to two decimal places. use the formula . a. 4.47 a b. 0.22 a c. 20 a d. 0.05 a

A

Step-by-step explanation:

The formula that relates current, power and resistance is

Where

I is the current (in amperes)

P is the power (in watts)

R is the resistance (in ohms)

We know P = 500 and R = 25, we plug them into the formula and solve for I:

Correct answer is 4.47 Amperes, or choice A.
