Question

easy form of expression for resistance in series as well as circuits. ​

Answer 1

Explanation:

Same current will flow through all the resistors since they are connected in series. The total resistance of the circuit is equal to sum of individual resistances. Now the resistors in series combination can be replaced by a single resistor REQ of the value 6 Ω

Answer 2

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.
