Mark True' or False for following statements: (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, as we know that materials which allow electric current to pass through them are called conductors. All metals are good conductors of electricity, thus metals can pass electric current. (b) False, as jute is an insulator and hence current cannot pass through them. Thus, in a circuit we need conductors through which electric current can pass. (c) False, as thermocol is an insulator. Thus, electric current cannot pass through it.
