Simple Circuits

Answer the following questions. Be sure to show all your work. This activity is available below or in a printable version.

1. Use one battery and four identical resistors. Draw a schematic of a circuit that will have the same current in each resistor and draw the maximum possible current from the battery.

2. Use one battery and four identical resistors. Draw a schematic of a circuit that will have the same current in each resistor and draw the least possible current from the battery.

3. For the circuit below, the battery has 9 volts and the three resistors are 3 Ω, 6 Ω, and 9 Ω. Calculate the total resistance of the circuit and the total current the battery delivers. Show your work.

4. For the circuit below, the battery has 6 volts and the three resistors are 2 Ω, 4 Ω and 6 Ω. Find the current through the 4 Ω resistor and the voltage drop across the 6 Ω resistor.
