3. Base your answers to the following questions on the information and data table below. Three lamps were connected in a circuit with a battery of constant potential. The current, potential difference, and resistance for each lamp are listed in the data table. [There is negligible resistance in the wires and battery.] Device Lamp 1 Lamp 2 Lamp 3 Current (A) 0.45 0.11 0.28 Potential Difference (V) 40.1 40.1 40.1 b) What is the potential difference supplied by the battery? Resistance (2) 89 a) Using standard circuit symbols, draw a circuit showing how the lamps and battery are connected. c) Calculate the equivalent resistance of the circuit. 365 143 d) If lamp 3 is removed from the circuit, what would be the value of the potential difference across lamp 1 after lamp 3 is removed? e) If lamp 3 is removed from the circuit, what would be the value of the current in lamp 2 after lamp 3 is removed?
