    Question

    "N” number of resistors of resistance R are connected in parallel across the voltage “V”, then which of the following statements is correct?

    1. The total voltage in the circuit is zero.
    2. Current in each resistance will divide equally among the resistors.
    3. Voltage across each resistor will divide equally among the resistors.
    4. Current will be very high.

    Hint:

    In parallel circuits, the current is branched out and recombined when branches meet at a common point. 

    The correct answer is: Current in each resistance will divide equally among the resistors.

      When "N” number of resistors of resistance R are connected in parallel across the voltage “V”, the current in each resistance will divide equally among the resistors.
      • The resistors in any circuit bear a constant voltage when a fixed amount of voltage is supplied.
      • In a parallel circuit, with N number of resistors and R resistance, the applied current will divide and distributed equally among all the resistors.
      • So the voltage in each resistor of a parallel circuit is the same.
