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
36 Ohms
c
8 Ohms
d
16 Ohms
c. 8 Ohms
You can use Ohm's Law: Resistance (R) = Voltage (V) / Current (I).
In this case:
- V = 24 volts
- I = 3 amperes
So, R = 24 volts / 3 amperes = 8 Ohms.
