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
4 Ohms
b
16 Ohms
c
8 Ohms
d
36 Ohms

Answer 1

The correct answer is c) 8 Ohms.

We can use Ohm's law to solve this problem:

Resistance (in Ohms) = Voltage (in Volts) / Current (in Amperes)

In this case, the voltage is 24V and the current is 3A, so:

Resistance = 24V / 3A = 8 Ohms.
