Hello, another homework question here. There are 5 resistors connected in a series circuit.
R1= 70 ohm
P1= 5 w
R2= 20 ohm
P2= 5 w
R3= 100 ohm
P3= 5 w
R4= 50 ohm
P4= 5 w
R5= 50 ohm
P5 = 5 w
The question is, "What is the maximum supply voltage that can be applied to the circuit before the limiting resistor burns open?"
I have determined that the limiting resistor is R3 because it has the lowest current rating. How do I solve this question? Do I take the limit current of R3 and multiply it by R3 to come up with the answer?
Any help is greatly appreciated. I have been stuck on this for some time now.
