Give the definition of electromotive force of an electric cell in open circuit.

What is the importance of insulators in household wiring?

If 5 ampere current is conducted for 30 seconds through any conductor then the total conducted charge would be (a) 6 coulomb (b) 150 coulomb (c) 300 coulomb (d) 30 coulomb
