Resistance

We need to find the equivalent resistance between points and in the given circuit.
Step 1: Identify the circuit configuration.
The circuit is a Wheatstone bridge with resistors: , , , , and .
Step 2: Check if the bridge is balanced.
The bridge is balanced, so no current flows through the 6 resistor.
Step 3: Simplify the circuit.
and in series: .
and in series: .
These two 6 branches are in parallel between and :

Step 4: Find resistance between and .
In the balanced bridge, the resistance between and is:
Path : 3 .
Effective resistance considering the parallel paths: Final Answer:

Step 1: Use the formula for two resistors in parallel Step 2: Substitute the given values
