a 120 V
Ohm's Law states that Voltage = Current x Resistance. Therefore, the voltage in the hairdryer is calculated as follows:
Voltage = 15 A x 8 ohms = 120 V
Therefore, the correct answer is a) 120 V.
The current in a hairdryer measures 15 A the resistance of the hairdryer is eight ohms. What is the voltage
a 120 V
b 0.5 V
c 7 V
d 1800 V
