Question

Q2)Differrntiate between
resistors connected in series
and resistors connected in
parallal​

Answer 1

In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together

Answer 2

Answer:

The total resistance of resistors connected in series is the sum of the resistance of all resistors. The total resistance of resistors connected in parallel​ is the reciprocal of the sum of the reciprocals of the resistance of all resistors.

If there are three resistors having resistance R1, R2 and R3, their total resistance tR is: Series ⇒ tR = R1 + R2 + R3

                          Parallel ⇒ 1/tR = 1/R1 + 1/R2 + R3

                                             tR = Reciprocal of (1/R1 + 1/R2 + R3)

The total resistance of resistors connected in series is always greater than any one individual resistor's resistance.  But, the total resistance of resistors connected in parallel​ is always smaller than any one individual resistor's resistance.
