In a network as shown in the figure the potential difference across the resistance 2R is (the cell has an emf of E and has no internal resistance):

A

`2 E`

B

`(4 E)/(7)`

C

`(E)/(7)`

D

E

Text Solution

Verified by Experts

Effective resistance across 2 R is `(2 R xx 4 R)/(2 R + 4 R) = (4 R)/(3)` . So PD will be in the ratio `R : (4 R)/(3)` or `3 : 4`

Assertion:- To cells of unequal emf E_(1) and E_(2) having internal resistances r_(1) and r_(3) are connected as shown in figure. Then the potential difference across any cell cannot be zero. Reason:- If two cells having nonzero internal resistance and unequal emf are connected across each other as shown, then the current in the circuit cannot be zero.
