Question

The internal resistance of five cells is 2.8 ohms each. The cells are connected as shown in the diagram to a 4-ohm resistance. What current, to the nearer hundredth, exists in the circuit?

1=
(E)(ns)
(r)(ns) + R
where
R
=4ohms
E-voltage of one cell in volts
ns-number of cells in series
= internal resistance of one cell in ohms.
R = resistance of external circuit in ohms
i = current in amperes
SWITCH
CELLS
EACH CELL- 2.5 Volts
