Question

reading of ammeter and voltmeter ​

Answer 1

Answer:

v=5volt

I=5/3

Explanation:

total resistance across ammeter=5+6+1=12ohm

potential provided to the circuit=20volt

i.e.,I=V/R

I=20/12

=5/3ampere

voltage across 3 ohm resistance is

total resistance =3ohm

current=5/3A

V=IR

V=5volt
