WebDec 10, 2024 · Have each student team take a battery, a light bulb, light bulb holder and a piece of wire. Using wire strippers or sandpaper, carefully remove about 1/4-3/8 in (approximately 6-10 mm) of insulation from the ends of the wire. Try to connect the battery, light bulb, light bulb holder and wire so the bulb lights up. Use tape if necessary. WebTo see how the brightness of bulbs change as they are connected in series and parallel, and to measure the potential difference across the bulbs and the current through the bulbs in series...
WebThe brightness is related to the power dissipated by the bulb. P = (I^2)R. So if you have more current (less R) the bulb will be brighter. Can you use more than 3 bulbs?
