Question 16 Mark ‘True’ or ‘False’ for the following statements & give reason for your answer
(a) Electric current can flow through metals.
(b) Instead of metal wires, a jute string can be used to make a circuit.
(c) Electric current can pass through a sheet of Thermocol.
Answer
(a) True; Metals are good conductors of electricity. So, an electric current can easily flow through them.
(b) False; Jute string is a bad conductor of electricity which means it does not allow electric current to flow through it. Hence, it cannot be used to make a circuit.
(c) False; Thermocol is a bad conductor of electricity. Hence, electric current cannot pass through it.
