Fast for brainliest the current in a hair dryer measures 21 amps. the resistance of the hair dryer is 15 ohms. what is the voltage?

For this case we have a problem where we must apply the Ohm Law, this law states:

Where:

The units of these three magnitudes in the international system of units are, respectively, volts (V), amps (A) and ohms (Ω).

According to the statement our data are:

amps

ohms

We want to find the voltage, like this:

(amps * ohms)

volts

V = 315 volts

570, the answer is 570, hope it
