This experiment will investigate how the brightness of bulbs changes depending on whether they are arranged in series or parallel. Circuit 3. Ammeter on each branch, voltmeter across each bulb Circuit ...

A 6-V battery powers a circuit with parallel branches on a board. Several wires and light bulbs plug into the board to make various series and parallel circuits. The brightness of the bulbs changes ...

Power is the energy transferred per unit time. Power is measured in watts (W), energy in joules (J) and time in seconds (s). 1 W = 1 J/s (1 watt is 1 joule per second.) Electrical power can be ...
