Your toaster has a power cord with a resistance of 2.2x10^−2 ω connected in series with a 9.7 ω nichrome heating element. the potential difference between the terminals of the toaster is 120 v.
1. how much power is dissipated in the power cord?
pcord = w
2. how much power is dissipated in the heating element?
phe= kw
