Question

Section A (Reading) 5

Electricity is generated in the power stations and then taken to buildings by

mains or supply cables. For the electricity to flow along the cables,it must

have a circuit.The circuit must be complete. Any interruption or break would

stop the flow of electricity.

The circuit is formed by the wired conductors inside the cable.

These wires are made of metal ,often copper. As metal is a good conductor

of electricity ,it allows the electricity to flow freely. The conductors are

covered by another material, a kind of plastic, which does not conduct electri-

city and is called an insulator.

This insulator stops the wire from touching and

prevents the electricity from flowing into the earth. The electricity flowing

along a wire is called an electric current, and the amount flowing per second

along a wire is measured in amperes. The electric current and its force is

measured in volts .Electric power is measured in watts .One thousand watts

make a kilowatt.

Based on your understanding of the passage , answer the following questions.

Answer the questions.

i What is an insulator ? 1
