Question

d. The current passing through a battery connecting, 5 cells through parallel
connection is 45 A. Calculate the current passing through a single cell.
​

Answer 1

Answer:

If two cells of different EMFs(instead of equal EMF) are connected in parallel across a resistor, what would be the current passing through the resistance.

Explanation:

E1 and E2 are respective EMFs, r1 and r2 the internal resistances of respective cell; R be the external resistor. then it is not difficult to calculate the current I through R=1/R.(E1.r2+E2.r1)/(r1+r2). Thus when E1=E2 and r1 and r2 negligible, we get I=2E/R
