| How much electric power is consumed by a 80-Ω soldering iron operating at 110 V? |
Electrical power consumed:
P = V^2 / R
Substitute given values
P = ( 110 V )^2 / 80 Ω
P = 151.25 watt

The corroded contacts in a lightbulb socket have 8.3 Ω total resistance. Part A How much actual power is dissipated by a 110 W (120 V) lightbulb screwed into this socket? Express your answer using two significant figures.
Suppose 55 kW is to be transmitted over two 0.135 Ω lines. Estimate how much power is saved if the voltage is stepped up from 170 V to 1700 V and then down again, rather than simply transmitting at 170 V. Assume the transformers are each 99% efficient.
Suppose 55 kW is to be transmitted over two 0.150 Ω lines. Estimate how much power is saved if the voltage is stepped up from 160 V to 1600 V and then down again, rather than simply transmitting at 160 V . Assume the transformers are each 99% efficient. Psaved = __________kW
