Question

A current of 10.8 A flows through an electric heater operating on 220 V. What is the heater's resistance?

Answer 1

Answer:

20.37Ohms

Explanation:

Hello! To solve this exercise it is fundamental to know the law of OHM, this law indicates that the voltage is equal to the product of the resistance that opposes the passage of energy by current passing through a conductor, the equation is as follows

V=IR

Where

I=current=10.8A

V=voltaje=220V

R=Resistance

solving for R

$R=\frac{V}{I} \\R=\frac{220}{10.8} =20.37Ohms$
