A cell and two resistors `R_1 and R_2` are provided to you. Derive an expression for the effective resistance of the circuit in which current is the same in both resistors.

A cell and two resistors R_1 and R_2 are provided to you. If R_1 = 4Ω and R_2 =6Ω . in which combination effective resistance is minimum? Find its value?

A cell and two resistors R_1 and R_2 are provided to you.Draw different combinations of resistors using R_1 , R_2 , and the cell.

Three resistors R_1, R_2, R_3 are to be combined in parallel connection. Arrive at the expression for the effective resistance of parallel combination.

Resistance are used to reduce the current flow in a circuit. Resistance can be connected in series and parallel to obtain the required value of resistance. Derive an expression for the effective resistance when three resistors are connected in parallel.

You are supplied with a galvanometer, resistor and some connecting wires. : Find the expression for the shunt resistance in the circuit.
