Answer 2

The resistance of the heater is (C) 12 ohm.

Given - Current and voltage

Find - Resistance

Solution - Resistance can be calculated using voltage and current by the mentioned formula -

V = I R

V is voltage, I is current and R is resistance.

R = 120/10

Performing division

R = 12 ohm

Hence, the resistance of the heater is (C) 12 ohm.
