An electric appliance draws 3 amperes of current when it is connected to a 24-volt source. What is the resistance of this appliance?
a
4 Ohms
b
16 Ohms
c
8 Ohms
d
36 Ohms
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.
