Answer 23 What is – series ? Question 24 Circuit which has all wires connected to make a full path . Answer 24 What is – closed ? Question 25 The power source for a circuit . Answer 25 What is – battery? 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.
