Answers

Answer 1

R1+R2+R3 =1+1+1=3 is used to represent the circuit's overall resistance.

The 3 resistors on the upper side of the circuit are linked in series in this instance, and the total resistance R1 is expressed as 1+1+1=3.

The combined resistance R2 is expressed as 2+2+2=6 due to the series connection of the three 2-ohm resistors on the lower part of the circuit. The intermediate resistances R1, R2, and 2 are linked in parallel. This parallel connection's total resistance, R3, is therefore represented as 2/1+ 2/1+ 6/1 = 1/1=1 ohm.

In other words, the closed loop's resistance is decreased to 1 ohm.

Now, R1+R2+R3 =1+1+1=3 is used to represent the circuit's overall resistance (R).

As a result, the resistance in the circuit from point A to point B is 3.
