What you need
micro-electricity kit, two multimetersWhat to do
TO INVESTIGATE
1. Use components from your microelectricity kit to set up the circuit shown in the diagram on the
right. You may remove (or add) resistors to this circuit as you work through the tasks.Task 1 Investigate what happens to:
a) the total current in the circuit, when a different number of resistors are connected in parallel and b) the current in each resistor connected in the circuit.Task 2 Investigate what happens to:
a) the potential difference supplied by the source of power and b) the potential difference across each resistor connected in the circuit.Task 3 Investigate what happens to the total resistance (V/I), in the circuit, as you add more resistors in
parallel.Record your measurements and observations.
SUMMARISE
2. Summarise what have you discovered in this Activity, about
a) the current in a parallel circuit, b) the potential difference across components in a parallel circuit and c) the total resistance of a parallel circuit.COMPARE SERIES AND PARALLEL CIRCUITS
3. a) Compare the current in a parallel and in a series circuit and explain the differences. b) Compare the potential difference across components in a parallel and in a series circuit. c) Compare the total resistance in a parallel and in a series circuit. d) What happens when you remove one component from either a series or a parallel circuit?Explain.
