Question

(I) What is the resistance of a toaster if 120 V produces a current of 4.6 A?

Answer 1

Answer #1

According to Ohm’s law, the relation between the resistance, current, and the potentialis given by the following expression.

Rearrange the above expression for resistance:

Substitutefor, andfor.

Hence, the resistance of the toaster rounds off to two significant figures is.
