Equivalent Resistance Calculator: This online equivalent resistance calculator simplifies the time-consuming task of calculating the resistance of series and parallel blocks in a single circuit several times. Easily determine the total resistance of a resistor circuit.Any such network's equivalent resistance will be a single resistor that has the same effect as the complete network.

Equivalent Resistance Definition and Formula

An equivalent resistance is defined as the total of the resistances of all the resistors in a circuit. The resistors can be wired in a series or parallel configuration. Assume that the three resistors are R1, R2 and R3.

The equivalent resistance is obtained by when these three resistors are linked in series: Re = R1+R2+R3.

The equivalent resistance is obtained by when these three resistors are linked in parallel:(1/Re) = (1/R1)+(1/R2)+(1/R3).

  • Where, R is the parallel resistance equivalent.
  • R1, R2 and R3 are the individual resistor resistances numbered 1, 2,..., n.

Equivalent Resistance Examples

Question 1: If one resistor is 3 Ohms and the other is 6 Ohms connected in parallel then calculate the equivalent resistance.

Solution:

Consider the problem,

We have the inputs are,

one resistor is 3 Ohms

other resistor is 6 Ohms

The Equivalent Resistance formula is given by: (1/Re) = (1/R1)+(1/R2).

(1/Re) = 1 / (1/3 + 1/6)

(1/Re) = 1 / (3/6)

(1/Re) = 6/3

(1/Re) = 2

Therefore, The Equivalent Resistance is 2 Ohms

FAQs on Equivalent Resistance Calculator

1. How do you compute two parallel resistors?

Take the reciprocal of their reciprocal values, put them together, and take the reciprocal once more.

2. Is the voltage in a parallel circuit the same?

Yes, the voltage is the same across all of the components in a parallel circuit.

3. Why does resistance drop at the same time?

Because the current has so many different pathways it might take, this phenomena occurs. Consider a store that adds multiple new check-out counters.
