Question

10. A battery of emf 4 volt and internal
resistance 12 is connected in parallel with
another battery of emf 1 V and internal
resistance 1 92 (with their like poles
connected together). The combination is
used to send current through an external
resistance of 2 Q. Calculate the current
through the external resistance.
[Ans: 1 A]​

Answer 1

Answer:

$6 \: is \: the \: answer$

Answer 2

Answer:

V 1 =4v

R 1 =1Ω

V 2 =1v

R 2 =0Ω

'Total current from the combination=current flowing 2Ω= i

I = v1-v2 / r1-r2 =3A

• Potential difference across 2Ω= (3×2)v = 6v

Explanation:

dear ....

A battery of emf 4 volts and internal resistance 1Ω is connected in parallel with another battery of emf 1 volt Combination is used to send current through an external resistance 2Ω. Calculate current through external resistance and potential difference across external resistance.

this is the right question

I hope it helps
