Question

2.
Resistors are connected as shown in
the circuit diagram.
The effective resistance between A and
B is:
4Ω
3Ω
A
3Ω
B
4Ω
3Ω
1) 3Ω
2) 3.5Ω
3) 11Ω
4) 5.5Ω​

Answer 1

Answer:

Calculating seperately the equivalent resistances,

1. R

CD

=R

CA

+R

AD

(Series connection)

⟹R

CD

=7+6=13Ω

2. R

EF

=R

EB

+R

BF

(Series connection)

⟹R

EF

=2+5=7Ω

Now,the equivalent resistors R

EF

and R

CD

are parallel,

Hence,

R

XY

=

R

EF

+R

CD

R

EF

×R

CD

⟹R

XY

=

7+13

7×13

=4.5Ω
