Question

2) Six equal resistors, each of value R are
joined together as shown in
fig. Calculate the equivalent resistance across
AB. If a supply of emf
E
is connected across AB , complete the current
through the
arms DE and AB.​

Answer 1

Answer:

Six equal resistors, each of value R are joined together as shown in figure Calculate the equivalent resistance across AB. If a supply of emfis connected across AB, compute the current through the arms DE and AB.

Answer 2

Answer:

AB =εReq=εR/2=2εR

DE=0

Explanation:

The equivalent resistance Req across AB is

1/Req=1/2R+1/2R+1/R=4/2R=2R or Req=R2

If a battery of emf ε is connected to AB, then current through arm AB =εReq=εR/2=2εR

Current through arm DE=0 (as Wheatstone bridge is in balanced state)
