How many different
branches can you have?
If you take out one light
bulb, what will happen to
the rest of the bulbs?
1. Draw a series circuit with TWO 1.5 volt batteries (right next to each other) and 3 resistors. One resistor is 2
ohms, one resistor is 3 ohms, and other resistor is 4 ohms.
2. Calculate the current flowing through the series circuit you drew above.
3. Calculate the total voltage of the series circuit you drew above.
4. Calculate the voltage drop across each resistor of the series circuit you drew above.
5. Draw a parallel circuit with THREE 1.5 volt batteries (right next to each other) and 2 resistors. One resistor is
3 ohms, one resistor is 5 ohms. Each resistor has its own branch.
6. Calculate the current flowing through each branch on the parallel circuit you drew above.
7. Calculate the voltage of the parallel circuit you drew above.
