1In a simple series circuit, why does the bulb light when you close the switch?
- ABecause the switch produces electricity .
- BBecause closing the switch completes the circuit.
- CBecause closing the switch breaks the circuit.
- DBecause voltage flows through the circuit.
2A simple series circuit consists of one 1.5V battery, wires and one bulb.
When the1.5V battery is replaced with a 3V battery:- Athe bulb glows brighter.
- Bthe bulb glows with the same level of brightness.
- Cthe bulb glows dimmer
- Dthe bulb "blows" and the circuit will no longer work.
3A material that lets electricity pass through it is called:
- Aan electrical conductor
- Ban electrical inductor
- Can electrical insulator
- Dan electrical appliance
4Which of the following materials is NOT an electrical conductor?
- Agold
- Bcopper
- Ccarbon
- Dphosphorus
5Which of the following materials is an electrical insulator?
- Alead
- Bbrass
- Crubber
- Daluminium
6In which circuit will the bulb or bulbs glow brightest?
- AA simple series circuit with one bulb and one battery
- BA simple circuit with one bulb and two batteries.
- CA simple series circuit with two bulbs and one battery
- DA simple circuit with one battery and two bulbs in parallel.
7Why is a bulb brighter when it is powered by two batteries in series rather than by just one battery?
- ABecause the flow of electric current in the circuit is less.
- BBecause the flow of electric current in the circuit is greater.
- CBecause the flow of voltage in the circuit is greater.
- DBecause the total voltage across the circuit is less.
