Question

What is equilaventresistance

Answer 1

More resistance means less current is flowing through the circuit.Equivalent resistance is a different way of indicating 'total' resistance, which we calculate differently for series and parallel circuits. In a series circuit, the different components are connected in a single, continuous loop.

Answer 2

In a circuit there could be a number of resistances, or other elements.  The  Equivalent resistance is the net effective resistance of all the elements taken into account, across two points in the circuit.
