Question

An electric heater draws 10 a from a 120-v line. the resistance of the heater is

Answer 1

v=l×r
120=10r
therefore r = 12

Answer 2

The correct answer is 12.

Given: Current (I) = 10 A.

Voltage (V) = 120 V.

To Find: The resistance of heater.

Solution:

As, we know that,

V = IR

120 = 10*R

R = 12 Ω

Hence. the resistance of heater is 12 Ω.
