4Which would conduct electricity best – a long wire or short wire?
5How well an object conducts electricity depends on 3 things How well an object conducts electricity depends on 3 things. What are they?The material of an objectThe length of an objectThe width of an object
6What happens to the remaining bulbs when 1 bulb burns out or is removed in a parallel circuit? The other bulbs remain lit.
7Which type of circuit has only one path for electricity to flow ? Series Circuit
20Is this an example of an insulator or conductor?
21What is the difference between a series and a parallel circuit ? Parallel Circuit – more than I path for electricitySeries Circuit – I path for electricity
22What happens to the remaining bulbs when 1 bulb burns out or is removed in a series circuit? The other bulbs go out.
23If a bulb in a circuit does not light, what could be the problem? Batteries notconnected properlyDead batteryOpen switchBroken bulb
24Why would a circuit wired with batteries have a brighter bulb than a circuit wired withbatteries ?The circuit with +-+- gets voltage from 2 batteries. The circuit with only gets voltage from 1 battery. 2 of the batteries with the negative sides together cancel each other out.
25What would the voltage be in the series circuit below? 4.5 volts
26What happens if 3 batteries are connected in a series circuit and 1 battery is connectedbackwards?2 batteries will cancel each other outleaving only the voltage from 1 battery
27What material is the best conductor of electricity ? Metal
28What is an open circuit? Circuit through which electricity does not flow because one part is notconnected.
