Homework Statement
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
Homework Equations
Number of resistors!
The Attempt at a Solution
P = V2 / x*R
x*7=1272/1800
x=1.28
so only one resistor can be connected.
