Question

Use Ohm's law to find the voltage needed to make a current of 3 A in a resistance of 9 ohms.

Answer 1

`\huge\boxed{\sf V = 27\ volts}`

Step-by-step explanation:

Given Data:

Current = I = 3 A

Resistance = R = 9 Ω

Required:

Voltage = V = ?

Formula:

V = IR (Ohm's Law)

Solution:

V = (3 A)(9 Ω)

V = 27 volts
