List of top Physics Questions on Combination of Resistors - Series and Parallel

The resistors of values \(3\Omega\), \(6\Omega\) and \(18\Omega\) are connected in parallel in a circuit. The equivalent resistance in the circuit is
A uniform wire of resistance 12 \(\Omega\) is cut into three pieces in the ratio of length 1: 2: 3. Now the three pieces are connected to form a triangle. A cell of emf 8 V and internal resistance 5 \(\Omega\) is connected across the highest of the three resistors. The current through the circuit is:
From the combination of resistors with resistance values $ R_1 = R_2 = R_3 = 5 \, \Omega $ and $ R_4 = 10 \, \Omega $, which of the following combination is the best circuit to get an equivalent resistance of 6 $ \Omega $?
In the following figure, the equivalent resistance between ‘A’ and ‘B’ will be
equivalent resistance between ‘A’ and ‘B’
Two resistances combine in series order to provide 50 ohms resultant resistance, and when they combine in parallel order, they provide 8 ohms resultant resistance. Then the value of each resistance is:
A wire of resistance 20 \(\Omega\) is divided into 10 equal parts. A combination of two parts are connected in parallel and so on. Now resulting pairs of parallel combination are connected in series. The equivalent resistance of final combination is _______ \(\Omega\).
