List of top Physics Questions on Combination of Resistors - Series and Parallel asked in CUET (UG)

Four resistors of \(8\,\Omega\) each are connected in parallel. Then five such equivalent combinations are connected in series. What will be the total resistance?

A uniform wire of resistance \(R\) is cut into four equal parts. These parts are then connected in parallel. The equivalent resistance of the combination is:

A wire of uniform cross-section \(A\), length \(l\) and resistance \(R\) is bent into a complete circle. The equivalent resistance between any two diametrically opposite points will be:

Choose the correct combination of three resistances \(1\ \Omega\), \(2\ \Omega\) and \(3\ \Omega\) to get equivalent resistance \(\dfrac{11}{5}\ \Omega\).

For the given mixed combination of resistors, calculate the total resistance between points \(A\) and \(B\).

A wire of uniform cross-sectional area and resistivity has total resistance \(36\,\Omega\) and is bent into a circle as shown in the figure. The equivalent resistance between points \(A\) and \(B\) is:

The equivalent resistance of the following combination of resistances between \(A\) and \(C\) is:

Five resistors, each of resistance \(R\), are connected between points \(A\) and \(B\) as shown in the figure. The equivalent resistance between \(A\) and \(B\) is:

In the figure shown, three resistors of \(4\,\Omega\) are connected. If point \(D\) divides the resistor between \(B\) and \(C\) into two equal parts, then the equivalent resistance between points \(A\) and \(D\) 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:

10 resistors, each of resistance R are connected in series to a battery of emf E and negligible internal resistance. Then those are connected in parallel to the same battery, the current is increased n times. The value of n is:
