calculate the effective resistance
10.33 Ω
What is the term for the rate of flow of charge around a circuit?
current
calculate the effective resistance
5Ω
Why is it dangerous to touch a live wire and the ground?
A current will flow through you. This can interrupt the rhythm of your heart and cause burns.
what is an insulation?
non-conductive material or substance that resists the flow of electric current.
calculate the effective resistance
2.73 Ω
What colour is the live wire, neutral wire and earth wire in a plug?
live wire - brown, neutral wire - blue, earth wire - green yellow
Would a plug still work without the earth wire?
Yes, the earth wire is for safety
What is the term for the rate of energy transfer?
Power
What is a fuse?
A piece of wire which will melt and break the circuit if too much current is flowing.
calculate the effective resistance
3/5 Ω
calculate the effective resistance
10 Ohms
What is the term for the "energy transferred per unit charge"?
potential difference (p. d.) / Voltage
