The current in a hair dryer measures 15.0 amps. the resistance of the hair dryer is 8 ohms. what is the voltage? v = i x r

Keywords:

Hair dryer, current, resistance, voltage , Ohm's Law

For this case we have that the current of a hair dryer is 15 Amps, while its resistance is 8 ohms. They ask us to find the voltage of the hair dryer. We have that, by definition, Ohm's Law states that:

Where:

Substituting we have:

Thus, the voltage of the hair dryer is 120 volts.

explanation:

v=uf/(u-f)
