1. The problem statement, all variables and given/known data The Potential drop across a light bulb in a circuit is 5.6 volts. After 12C of charge have passed through the bulb how much electrical energy will the bulb have received? Any help would be much appreciated 3. The attempt at a solution im not really sure of what formula to use.. Q=IxT or Q=IxT but seeing that theres not time in the question im pretty confused..
