Final Jeopardy
A 100-watt incandescent lamp,
when hot, has a resistance of 42
ohms, while a 60-watt lamp has a
resistance of 823 ohms. Compute
the current through each lamp
when they are connected in
separate circuits and operated from
a 220-volt line.
Final Jeopardy
Answer
Current = Potential difference / resistance
(100 watt bulb) 220 / 42 = 5.24 A
(60 watt bulb) 220 / 823 = 0.27 A.
