Question

How do you calculate the total electrical power?

Answer 1

Explanation:

In series and parallel circuits:

1. In a series circuit, all components are connected end to end, forming a single path for current flow.
2. In a parallel circuit, all components are linked across each other rather than end to end, creating exactly two sets of electrically common points.
3. The SUM of the power lost by each resistor makes up the total power in a series circuit.

The formula for total power,

$\Rightarrow P_{Total}={\mathrm{P}}_1+{\mathrm{P}}_2+{\mathrm{P}}_{3......}+{\mathrm{P}}_{\mathrm{n}}$

Hence, the sum of all the power utilized by each individual resistor is used to compute the overall power.
