Kirchhoff's two Rules for analyzing DC circuit are the following: #1. In a closed loop of electric circuit, algebraic sum of rise and fall in potential (or voltage) is zero. What will happen if the rule is not valid? Explain. #2. Current entering a junction is equal to the current leaving the junction in a circuit. What will happen if it is not true? Explain. 1. Predictions by inquiry and group discussion Let current I pass through the bulb before connecting the wire with two alligator jacks across the bulb. Will the current I pass through the bulb in the circuit after connecting the wire as shown? If“yes” why and if “no” why not? (b) Two identical bulbs in series are lighted when connected to a battery with switch open as shown. What will happen if the switch is closed? Explain.
