1. The problem statement, all variables and given/known data How many resistors, R = 70 ohms can be connected in a series circuit when the maximum power loss of the circuit is 1800W. and the voltages supply is 127V 2. Relevant equations Number of resistors! 3. The attempt at a solution P = V2 / x*R x*7=1272/1800 x=1.28 so only one resistor can be connected.
