Question

Compare the equivalent resistance of two or more resistances in parallel with the individual resistances and justify it.

Answer 1

Answer:

Equivalent resistance is more than either of the two resistances when they are connected in series. Components connected in series are connected along a single path, so the same current flows through all of the components.  The current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component.

In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. A circuit composed solely of components connected in series is known as a series circuit. The total resistance of resistors in series is equal to the sum of their individual resistances.  

Hence, the equivalent resistance is more than the individual resistances because a sum is taken of all the individual resistances.

$R_{total} = R_{1} + R_{2}\\\\I = I_{1} + I_{2}$

Answer 2

Answer:

Equivalent resistance is more than either of the two resistances when they are connected in series. Components connected in series are connected along a single path, so the same current flows through all of the components.  The current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component.
