1. PRACTICE (WB) 1)Four resistors in series. Choose voltage for your battery. Determine I and V across each resistor. 2)Four resistors in series. Chose I in one of the resistors. Determine I and V across each resistor and voltage of the battery. 3)Four resistors in series. Chose potential drop across one of the resistors. Determine I and V across each resistor and voltage of the battery.

2. PARALLEL CONNECTION Construct the illustrated circuit and draw its diagram. Show direction of the current on the diagram. Unscrew one of the bulbs and observe what happens with the brightness. Add a third light bulb to the circuit. Observe what happens with the brightness. Make a conclusion about the current through each bulb. Use a V-meter to find potential drop across each bulb. Make a conclusion
