SERIES+AND+PARALLEL+CIRCUITS+ACTIVITY

Back to IGCSE PHYSICS > ELECTRICITY > ENERGY AND POTENTIAL DIFFERENCE == =MEASURING CURRENT IN A CIRCUIT= [|AC CIRCUIT CONSTRUCTION KIT] ACTIVITY A: Create three different circuits with a 9.0 volt battery and three bulbs connected in different combinations of series and parallel. Measure the current in each wire. ACTIVITY B: In each circuit, replace a bulb with a resistor and see if there is any difference.

ACTIVITY C: What happens to the currents if you add a battery in parallel? A battery in series?

ACTIVITY D: Create the first circuit below (change battery to 30 volts). Measure current as shown. Then add 2 bulbs as shown and measure current in each branch. Repeat for third circuit. CONCLUSION FOR SERIES AND PARALLEL CIRCUITS ACTIVITY
 * 1) What can you say about the current in a series circuit?
 * 2) What about the currents in the different wires of a branching circuit?
 * 3) What happens to the current if you replace a 10Ω bulb with a 10Ω resistor?
 * 4) What are the different energy changes in the bulb and resistor?
 * 5) What happens to the current in a circuit if you add a battery in parallel with another battery?
 * 6) What happens to the current in a circuit if you add a battery in series with another battery?
 * 7) What happens to the current in a component when you add others in series?
 * 8) What happens to the current in a component when you add others in parallel?
