Electric Heater Current Calculation

How much current does the portable electric heater draw?

The current in the electric heater is 12 A.

Current is directly proportional to the voltage flowing in any circuit and resistance of the resistor is the proportionality constant. This is in accordance with Ohm's Law. The current can be determined by the ratio of voltage to resistance.

Current = Voltage / Resistance

As V = IR

Given that the resistance of the electric heater is 10 ohms and it plugs into a 120 V wall outlet, we can calculate the current as follows:

Current = 120 V / 10 ohms = 12 A

Therefore, the current drawn by the portable electric heater is 12 amps.
