Answer 2

Answer: Effective resistance for resistors in parallel is the reciprocal of the sum of the reciprocals of the individual resistances

Explanation:

For a connection of resistors in parallel p.d across all the resistors will be the same.

and the current across flowing across the resistors will be the sum of the current flowing through each resistor.

So let total current be 'I' and individual resistances be R1 ,R2 and R3

    I=I1+I2+I3

    V/R=V/R1+V/R2+V/R3  [from Ohm's law I=V/R]

    V/R=V(1/R1+1/R2+1/R3)

    1/R=1/R1+1/R2+1/R3  [cancelling V from both sides]
