What is the voltage across a resistor
oltage across a resistor of 3 ohms that carries a current of 15 amps? need to know asap

45 V

Explanation:

The voltage across the resistor can be found by using Ohm's law:

where

R is the resistance

I is the current

In this circuit,

Therefore, the voltage across the resistor is

Voltage = (current) x (resistance)   <== memorize this formula

Voltage = (15 Amperes) x (3 ohms)

Voltage = 45 volts
