A hair dryer operate at 1800 watts along with a 240 watt power resistor connected in a series. Utilizing a 120 volt source, determine the following:
a.) sketch of the circuit
b) The current I and resistance R of the hair dryer
c) The individual resistance Ri and the Voltage drop Vi across each component in the circuit
d) the cost of operating the hair drer if it were left running for one weel.... at a rate of 9.2 ? per KWH
