Question

What is effective resistance?

Answer 1

Resistance:

A resistor seems to be a two-terminal passive electronic equipment that provides electrical resistance as just a circuit element. Resistors throughout circuits reduce current flow as well as lower voltage fluctuations.

The formula for effective resistance:

In a complicated circuit with two or maybe more resistors, this same effective resistance is calculated by adding the total resistance of all the resistors throughout the circuit.

The resistors could be connected in either a parallel or serial manner.

Series combination:

$\mathrm{R}={\mathrm{R}}_1+{\mathrm{R}}_2+...+{\mathrm{R}}_{\mathrm{n}}$

Parallel combination:

$\mathrm{R}=\frac{1}{{\mathrm{R}}_1}+\frac{1}{{\mathrm{R}}_2}+...+\frac{1}{{\mathrm{R}}_{\mathrm{n}}}$.
