Question

Calculate the effective resistance of the given circuit across
terminals AC
​

Answer 1

Answer:

5 ohm

Explanation:

as 5 ohm and 5 ohm through B are in series thus 5+5=10

and then 10 and 10 are in parallel so that

effective resistance = 10×10/10+10

=100/20=5 ohm

Answer 2

Answer:

Rs= R1+R2

= 5+5

= 10 ohm in symbol

1/Rt= 1/10+ 1/10

=0.1+ 0.1

1/Rt = 0.2

Rt=1/0.2

=5ohm in symbol
