How many cells each marked `(6V-12A)` should be connected in mixed grouping so that it may be marked `(24V-24VA)`

A

4

B

8

C

12

D

6

Text Solution

Verified by Experts

The correct Answer is:

A

number of rows `=("required current")/("given current")`
`=(24A)/(12A)=2=m`
Number of cells in each now
`=("required potential")/("given potential")`
`=(24)/(6)=4=n`
`therefore` Total no of cells `=nxxm`
`=2xx4=8`
