Question

A bettety of EMF 4v and internal resistance 1ohm is connected with three 45 ohms resistance a voltmeter and an ammeter in the electrical circuit as shown in the figure The reading of the voltmeter and ammeter

Answer 1

Answer:

ANSWER

Current in the circuit is I=

r+R

E

=

r+2

4

=1

or 2+r=4

or r=2Ω

When the terminals of battery are connected directly, the current =E/r=4/2=2A
