Question

How to calculate resistance in series​

Answer 1

Explanation:

Resistance in series is calculated as the sum of all the resistors in a circuit.

Like :- R1 + R2 + R3....

More to know :-

Resistance in parallel is calculated as :-

1/R1 + 1/R2 + 1/R3

In houses, the circuits are connected in parallel. It is so because , in series , the resistors is horizontally. So , to on any one electric appliance , we have to on all. And if we want to off one electrical appliance , we have to off all. Moreover, if one electrical appliance breaks , all other will not work as the current has only one path to go. But in the case

of parallel circuit , there are more than one path for the current to go.

So , in houses the resistance is connected in parallel.

Answer 2

Explanation:

You can find TOTAL RESISTANCE in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + ... " Before we get into the calculations, remember what we said at the start of this section: "The total resistance of a parallel circuit is NOT equal to the sum of the resistors (like in a series circuit).
