Question

show how would you join three resistors each of rezistors 9-2 so that the equivalent resistance of the combination is (a) 12.5-2 (b) 6-2
​

Answer 1

Answer:

ANSWER

Resistance of each resistor R=9Ω

Two resistor connected across A and B are connected in parallel.

Equivalent resistance across A and B R

AB

=

R+R

R×R

=

2

R

=

2

9

=4.5Ω

This equivalent resistance is connected in series to another resistor R.

So equivalent resistance across A and C R

AC

=R

AB

+R=4.5+9=13.5Ω
