उत्तर

Parallel circuit: This is so because in a parallel circuit, if one bulb does not work properly, it does not affect the working of the other bulbs.

(Ammeter/ Voltmeter) 

True or False – If False give the correct answer

The representation of the electric current is A


Conventionally, the direction of the current is taken as:


A current of 1 A is drawn by a filament of an electric bulb. Number of electrons passing through a cross section of the filament in 16 seconds would be roughly


An ammeter is always placed in parallel with the circuit.
