SATHEE: Current Electricity 1 Question 20

Current Electricity 1 Question 20

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, $\frac{1}{R_{e q}} = \frac{1}{2 R} + \frac{1}{2 R} + \frac{1}{R} = \frac{2}{R}$

$∴ R_{e q} = \frac{R}{2}$
