Question

A cell 2V and negligeble Resistance is
connected as an electrical circuit
show in the figure calculate the current
flowing, throughs each resistance and
through the cell​

Answer 1

Answer:

0.25A

Explanation:

The equivalent resistance across the cell =2∣∣(2+

4+4

4×4

)Ω

⟹R

eq

=2∣∣(2+2)Ω

⟹R

eq

=

2+4

2×4

⟹R

=

3

4

Since , V=IR

⟹I=

R

V

So, current through the cell =

(

3

4

)

2.0

⟹I=1.5 A

Therefore the current through the lower branch =

6

2

×1.5

=0.5 A

Since the resistance are equal i,e, 4Ω

So, the current will equally divide in each branch.

So I=

2

0.5

⟹I=0.25A
