Mark 'True' or 'False' for following statements:
- Electric current can flow through metals.
- Instead of metal wires, a jute string can be used to make a circuit.
- Electric current can pass through a sheet of thermocol.
Answer:
(a)
Metals are good conductors of electricity , hence they allow the electric current to flow through them easily. Hence, an electric current can flow through metals.
So, the given statement is True.
(b)
Jute string is a bad conductor of electricity , hence it does not allow the electric current to flow through it. Hence, strings made of jute cannot be used to make circuits.
So, the given statement is False.
(c)
Thermocol is a bad conductor of electricity , hence it does not allow the electric current to flow through it. Hence, an electric current can not pass through it.
So, the given statement is False.
