Design circuits that demonstrate all of the principles listed below. Set up the circuits and
take measurements to show that the principle in question is indeed correct.
Principles of Series Circuits
1. The sum of the voltages across each circuit element equal that of the battery.
2. The current through each circuit element is the same.
3. Resistors with higher resistances have higher voltages across them.
4. Resistors added in series to any circuit increase the total resistance to current in
the circuit.
Principles of Parallel Circuits
1. Voltages across each circuit element are the same.
2. The sum of the currents through each parallel circuit element equal the current
through the battery.
3. Resistors with higher resistances have less current through them.
4. Resistors added in parallel to any circuit decrease the total resistance to current
in the circuit.
General Principles
1. A branch in a circuit that contains a short has no voltage across it.
2. A branch in a circuit that is open has the full voltage across it.
3. A battery is a constant voltage source.
4. A battery is not a constant current source.
5. Ammeters have very small internal resistance.
6. Voltmeters have very large internal resistance.
