The current in the electric heater is 12 A.
Step-by-step explanation:
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 the ohm's law. So current can be determined by the ratio of voltage to resistance. As the resistance is given as 10 ohms and the voltage is given as 120 V, then the current is
Current = V/R
As V = IR
Current = 120/10 = 12 A
So the current in the electric heater is 12 A.
