Question

Five cells are connected in series in a row and then four such rows
are connected in parallel to feed the current to a resistive load of
1.25 12. Each cell has an emf of 1.5 V with an internal resistance
of 0.2 22. The current through the load will be
​

Answer 1

Answer:

total five cells are therein series in a row // parallel lines so we have to add these numbers or see in the table of parallel lines or search in google

Answer 2

Answer:

5 a

Explanation:

Five cells are connected in series in a row and then four such rows are connected in parallel to feed the current to a resistive load of 1.25 Ω . Each cell has emf of 1.5 V with internal resistance of 0.2 Ω . The current through the load will be _____ .

1 A

5 A

15 A

None of the above

Correct Option: B

Req =

5 × 0.2

= 0.25

4

I =

5 . E

=

5 × 1.5

= 5 A

RL + Req 1.25 + 0.25
