Question

Q25.Two wires of resistance 2 ohm 2 points
and 4 ohm are connected in
parallel and are connected to a 2
volt battery,the current in the
circuit will be *
a) 2/3 Amp
b) 3/2 Amp
c) 10 Amp
d) None​

Answer 1

Two wire have resistance... one wire have 2ohm and another wire have 4 ohm both are connected in parallel combination so. 1/Req=1/2+1/4, 1/Req= 2+1/4, 1/Req= 3/4 Req= 4/3ohm .

V=2 volt , Req= 4/3 ohm then I =? , V= i×Req ,. 2= i×4/3 , I= 3/2 A
