The Resistance of the wire that makes up the heating element of the toaster is 13.75Ω.

What is Resistance?

Resistance is the measure of the opposition to current flow in an electrical circuit.

S.I. Unit of resistance is ohms, symbolized by the Greek letter omega (Ω)

Also from Ohm's Law,[tex]R=\frac{V}{I}[/tex]

From power-current relation

P=VI

Also, [tex]I=\frac{P}{V}[/tex]

[tex]I = \frac{1050}{120}[/tex]

I = 8.75 A

From Ohm's Law,[tex]R=\frac{V}{I}[/tex]

[tex]R = \frac{120}{8.75}[/tex]

R = 13.75 Ω

The Resistance of the wire is 13.75 Ω
