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

Answer:

R = 6.67 ohms

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

$R=\dfrac{V}{I}\\\\R=\dfrac{120}{18}\\\\R=6.67\ \Omega$

So, the resistance of the heater is 6.67 ohms.
