Question

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 PLEASE HELPPPPPPP​

Answer 1

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

Voltage = (15 Amperes) x (3 ohms)

Voltage = 45 volts

Answer 2

45 V

Step-by-step explanation:

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

`V=RI`

where

R is the resistance

I is the current

In this circuit,

`R=3 \Omega`

`I=15 A`

Therefore, the voltage across the resistor is

`V=(3\Omega )(15 A)=45 V`
