In the given circuit figure

A

the current through the battery is 5.0 A

B

P and Q are at the same potential

C

P is 2.5 V higher than Q

D

Q is 2.5 V higher than P

Text Solution

Verified by Experts

The correct Answer is:
A, D
a.,d.
Equivalent resistance of the circuit `= (2.5 + 1.5) = 4Omega`
Current through battery is `I = 20//4 = 5A`.
Current through P = Current through`Q = 5//2 = 2.5A`
` V_(A) - V_(Q) = 3 xx 2.5 = 7.5 V `.............(i)
`V_(A) - V_(Q) = 2 xx 2.5 = 5 V`..............(ii)
From Eqs. (i) and (ii), we get `V_(Q) - V_(P) = 2.5V` .
