Question

How to calculate the total resistance in series circuits?

Answer 1

Answer:

just add all the resistances. ie. r2+r2+r3+r4 and so on

Explanation:

Answer 2

RESISTANCE IN A SERIES CIRCUIT

In order to understand the process of calculating the resistance in a series circuit, we need to first understand what resistance and a series circuit mean.

Resistance :- The opposition to the flow of current in a circuit is known as resistance. Resistors are used in a circuit for resistance.

Series Circuit :- A close circuit in which the electricity flow follows only one path is known as a series circuit. The current throughout a series circuit is same.

Now, back to the question.

The total resistance in a series circuit is calculated by adding the values of all the resistances in the circuit.

(1) Given :-

   R1 = 27Ω

  R2 = 2200Ω

   R3 = 15Ω

   Rtotal = 27 + 2200 + 15 = 2242Ω

(2) Given :-

    R1 = 3300Ω

    R2 = 1500Ω

    R3 = 47Ω

    Rtotal = 3300 + 1500 + 47 = 4847Ω

(3) Given :-

    R1 = 3300Ω

    R2 = 3300Ω

    R3 = 3300Ω

    Rtotal = 3300 + 3300 + 3300 = 9900Ω
