Answer to Question #50350 in Electric Circuits for lizan
The engineer decides to put a 12.5Ω resistor in series with this 25Ω resistor.
What is the power dissipation now in the 25Ω resistor with the same supply voltage after the 12.5Ω resistor was added?
(clue - determine what the supply voltage is from the given information. Then you can either use the voltage divider theory to find the voltage now dropped across the 25Ω and then work out the power, or you can calculate the total current now drawn by both resistors and then work out the power across the 25Ω resistor!)
