20. The equivalent resistance between points $A$ and $B$ of the circuit given below is
$(1997,2 M)$
True/False
Show Answer
Solution:
- All the three resistances are in parallel.
Therefore, $\frac{1}{R _{eq}}=\frac{1}{2 R}+\frac{1}{2 R}+\frac{1}{R}=\frac{2}{R}$
$$ \therefore \quad R _{eq}=\frac{R}{2} $$
