An electric appliance draws 3 amperes of current when it is connected to a 24-volt source. What is the resistance of this appliance?

Question

a
36 Ohms
b
8 Ohms
c
4 Ohms
d
16 Ohms

Answer 1

c
4 Ohms

Ohm's Law is V = IR, where V is the voltage, I is the current, and R is the resistance.

Given:
V = 24 volts
I = 3 amperes

Plugging in the values, we get:
24 = 3R
R = 24 / 3
R = 8 Ohms
