Question

A transformer is connected to 120 volts. find the current if the resistance is 4800-ohms.

Answer 1

Step-by-step explanation:

Formula

E = I * R Substitute the givens into the formula

Givens

E = 120 volts

I = ?

R = 4800 0hms

Solution

Ohms law is a 3 letter equation that relates volts ohms (resistance) * current (in amperes)

E = i * R

120 V = I * 4800 ohms Divide both sides by 4800

120 V/4800 = I * 4800/4800 Divide

0.025 amps = I

Answer

I = 0.025 amps
