Question

A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?

PLEASE GIVE ME THE CORRECT ANSWER!! (no links please.)
0.83 Amps
1.2 Amps
2.0 Amps
22.0 Amps

Answer 1

1.2 amps :)

Step-by-step explanation:

A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?

Known:

• R = 10.0 Ω

• V = 12.0 V

Unknown:

• I = ???

I = V/R

= 12.0 V / 10.0 Ω

= 1.2 amps
