Question

4 resistance of 2 ohm each are joined end to end to form a square ABCD calculate the equivalent resistance of the combination between any two adjacent corners

Answer 1

Total number of resistance = 4

Each resistance value = 2 ohms

Now, we need to find resistance between any two adjacent corners.

While doing that, the three resistors will be in series and the remaining one will be parallel to the rest of the three resistors.

Hence, the three resistors in series = 2 ohms + 2 ohms + 2 ohms = 6 ohms

Now, the 6 ohms and 2 ohms will be in parallel.

$\frac{1}{R_e_q} =\frac{1}{2} +\frac{1}{6}$

$R_e_q = \frac{6}{4}$

R = 1.5 Ohms

Hence, the equivalent resistance is 1.5 Ohms
