HERE IS YOUR ANSWER

================================

♣ In a series circuit, the equivalent resistance is the algebraic sum of the resistances. The current through the circuit can be found from Ohm's law and is equal to the voltage divided by the equivalent resistance. The potential drop across each resistor can be found using Ohm's law.♣

Hope it helps.

Answer 2

Explanation:

Equivalent resistance is a different way of indicating 'total' resistance, which we calculate differently for series and parallel circuits.

Lets resistance R1, R2

, are connected in parallel resistance circuit. Then the equivalent resistance of the circuit is given by

Req = 1/R1 + 1/R2
