Question

Three 1,5 volt battery cells are connected in series and and ammeter and glove are added what is the total current

Answer 1

V=1.5v

Three battery are connected

Total voltage

$E=1.5\times3=4.5V$

Assume resistance=R ohm

$E=iR$

$i=\frac{E}{R}$

Put value

$i=\frac{4.5}{R} Amp\rightarrow(1)$

Total current flow in circuit represents equation (1)
