Question

A heating coil has a resistance of 22 Ω and can safely handle 15 A of current. What is the maximum voltage that it can be connected to without burning out?

Answer 1

330 v

Step-by-step explanation:

V=IR

V=22×15=330

Answer 2

`\huge\boxed{\sf V = 330\ V}`

Step-by-step explanation:

Given data:

Resistance = R = 22 Ω

Current = I = 15 A

Required:

Voltage = V = ?

Formula:

V = IR (Ohm's Law)

Solution:

Put the given data in the above formula.

V = (15)(22)

V = 330 V

It should have a maximum voltage of 330 V to avoid burning out.
