Question

6. Four resistance of 4 each are joined to form a square ABCD. Calculate the equivalent
resistance of the combination between any two adjacent corners.
​

Answer 1

2 ohms is the equivalent resistance

Answer 2

Heya!!

let's calculate equivalent resistance between point A and B

let the equivalent resistance of the Sections BC , CD And DA be req.

req = 4Ω+ 4Ω+ 4Ω

req = 12Ω

This 12Ω resistor is in // with 4Ω resistor So, equivalent resistance of the whole circuit be Req

Req = (1/12 ) + ( 1/4)

Req = 1/3

Req = 3Ω
