Question

--1:2) Two circuit (i) & (ii) are given below incircuit (i) the key is closed and in circuit(ii) the key is opencompare the current in 2 circuit.​

Answer 1

the equivalent resistance in circuit1 is

(R1R2) /(R1+R2).

potential difference is v

so current is =v(R1+R2)/R1R2

in circuit 2

current =0

so ratio is 0
