Answer 1

Answer:

Mark brainlist

Explanation:

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
