Question

Five resistors of resistance ‘R’ are connected such that they form a letter ‘A’. Find theeffective resistance across the free ends.

Answer 1

Answer:

Five resistors of resistance 'R' are connected such that they form a letter 'A'. Find the effective resistance across the free ends. Answer : ... Therefore, the total or the resultant resistance is = 8R/3 ohm

Answer 2

Dear Student,

◆ Answer -

Req = 8R/3

● Explanation -

Top 2 resistors are connected in series.

R' = R + R

R' = 2R

This combination of 2 resistors is connected in parallel to resistor in the middle.

1/R" = 1/R + 1/R'

1/R" = 1/R + 1/2R

R" = 2R/3

This combination is in turn is series combined with 2 resistors at the base.

Req = R + R" + R

Req = 2R + 2R/3

Req = 8R/3

Therefore, the effective resistance across free ends is 8R/3.

Thanks dear...
