# How can i calculate voltage drop in a parallel circuit?

##### 1 Answer

Well for that you need a circuit to show me,still I am giving you two examples with how to work out.

See the circuit below,

It is clear that,

So,current flowing through the circuit is

so,potential drop across each resistance can be calculated just by multiplying their resistance value with the current flowing through them.

thus

and,

or,you could have multiplied the current flowing through them with their equivalent resistance,i.e

In the example below, in the upper wire,

So,net resistance of thee upper wire is

and that of the lower wire is

So,net resistance of the circuit is

So,current flowing through the circuit is

now,volatge drop across the parallel combination of two

the same amount of voltage has been dropped across the upper wire,as both are in parallel combination.

So,we have to find the current flowing through the upper circuit in order to calculate that.

So,current flowing through the lower wire is

so,current flowing through the upper circuit is

So,potential drop across

So,the rest i.e
