Question

PLEASE HELP FAST FOR BRAINLIEST

Answer 1

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

$V = I * R$

Where:

• V: Voltage

• I: Current

• R: Resistance

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:

$I = 21$ amps

$R = 15$ohms

We want to find the voltage, like this:

$V = 21 * 15$ (amps * ohms)

$V = 315$ volts

Answer:

V = 315 volts
