The current in a hair dryer measures 25 amps. The resistance of the hair dryer is 14 ohms. What is the voltage?

Based on Ohm's law, the relation between the current, voltage and resistance can be described using the following equation:

Voltage = Current * Resistance

We are given that:

Current = 25 amperes

Resistance = 14 ohms

Substitute with the givens in the above equation to get the voltage as follows:

Voltage = 25 * 14 = 350 volts
