The potential difference across P and Q will be 6V.When connected in parallel,the voltage remains the same across all resistors.
Anonymous:
Points P and Q are in series
That doesnt matter,the resistors are connected in parallel,so only the across these resistors will vary not the voltage
we have to find voltage difference between P and Q its clearly given in the question...so first find V in P then find the voltage in Q
leave it ...its ok
Voltage varies when 'two' or more resistors are connected in series "with each other",then Voltage across these "individual' resistors vary.When resistor a connected in "parallel with each other" the current varies and voltage across each resistor remains the same..
These resistors whether connected in parallel or series are always in series with battery or power source
I hope ur confusion is resolved
oh and I think the current will never flow because the key or switch is closed ...have a look
And we argued over nothing..Lol

1/rp=1/R1+1/R2
=1/2+1/2=2/2
1/rp=1
I=V/R from V=IR
so,
V=6,R=1
6/1
=6A
=1/2+1/2=2/2
1/rp=1
I=V/R from V=IR
so,
V=6,R=1
6/1
=6A
You are supposed to find voltmeter reading
this is fully wrong infact..
