Download Solution PDFConcept:
When the terminals of two or more resistances are connected at the same two points and the potential difference across them is equal then it is called resistances in parallel.
The net resistance/equivalent resistance(R) of resistances in parallel is given by:
\(\frac{1}{R} = \frac{1}{{{R_1}}} + \frac{1}{{{R_2}}}\)
Application:
Given:
R1 = R2 = R
The equivalent resistance is given as:
\(\frac{1}{R_{eq}} = \frac{1}{{{R}}} + \frac{1}{{{R}}}\)
\(R_{eq}=\frac{R}{2}\)
