Question

Find the value of current 'I' in the given circuit.

Answer 1

Given:

Circuit diagram is provided.

To find:

Current in circuit?

Calculation:

• The two resistances are in parallel combination.

So, net resistance will be :

$\dfrac{1}{R} = \dfrac{1}{10} + \dfrac{1}{10}$

$\implies \dfrac{1}{R} = \dfrac{2}{10}$

$\implies \dfrac{1}{R} = \dfrac{1}{5}$

$\implies R= 5 \: ohm$

Now, current in circuit :

$\therefore \: i = \dfrac{V}{R}$

$\implies \: i = \dfrac{2}{5}$

$\implies \: i = 0.4 \: amp$

So, current in circuit is 0.4 Amperes.
