The animation above shows a circuit with two light bulbs connected in parallel. Turn on the light by clicking on the switches. Click here for a photo of a real circuit

Compare the brightness of these bulbs (with one battery) to the brightness of a single bulb (with one battery). Are they brighter, dimmer or the same?

Current

Add ammeters to the circuit. Close all the switches. Change the number of batteries and each time write down the currents shown on ammeters A, A1 and A2.

Can you find a pattern in your results?
