Question

What is the formula for parallel resistance?

Answer 1

Resistances and Resistors

1. When we connect resistors in parallel, the electric current splits to go via several branches.
2. Unlike resistors in series, the voltage decreases across each resistor will be equal.
3. Because there are many resistors linked in parallel, we must calculate the total resistance.
4. To do so, we must use the parallel formula to calculate the resistors.
5. Ohm's law is used to obtain the equation.
6. The equation for the electric current 'I' is provided by the law as $I=V/R$, where 'V' is the potential drop, and 'R' is the resistance of the circuit.

The formula for parallel resistance:

1. Resistors are said to as being in parallel when two nodes share terminal connections. Smaller than the matching total resistance is the smallest parallel resistor.
2. Parallel Resistor Equation: $\frac{1}{{\mathrm{R}}_{\mathrm{T}}}=\frac{1}{{\mathrm{R}}_1}+\frac{1}{{\mathrm{R}}_2}+\frac{1}{{\mathrm{R}}_3}\dots \dots +\frac{1}{{\mathrm{R}}_{\mathrm{n}}}\text{etc}$
