Question

The current in the circuit shown in figure . What will be the current in the circuit​

Answer 1

Answer: 0.1 A

Explanation:30+30=60

1/60+1/30=3/60=1/20

R=20 ohms

v=2V

I = 2/20

I= 0.1 A

Answer 2

Given,

Voltage = 2V

r1 = 30Ω

r2 = 30Ω

r3 = 30Ω

To find,

The current in the circuit

Solution,

The current in the circuit shown in the figure is 0.1 A.

We can simply find the current in the circuit by using the formula of

V = IR

r1 and r2 are connected in series so the resistance would be r4 = r1+r2

r4 (in series) =30+30

                    = 60Ω

r3 and r4 are connected in parallel so resistance would be

1/r5 = 1/r3+1/r4

      =  1/60+1/30

      = 3/60

       =  1/20

    r5  = 20Ω

    I = V/R

      = 2/20

      = 1/10

      = 0.1 A

Hence, The current in the circuit shown in the figure is 0.1 A.
