Question

electric heater carries a current of 18.0 A when operating at a voltage of 120 V. What is the resistance of the heater

Answer 1

R = 6.67 ohms

Step-by-step explanation:

Given that,

The current carried in the heater, I = 18 A

Voltage, V = 120 V

We need to find the resistance of the heater. Let the resistance be R.

We can use Ohm's law to find R.

V = IR

`R=(V)/(I)\\\\R=(120)/(18)\\\\R=6.67\ \Omega`

So, the resistance of the heater is 6.67 ohms.
