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.

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.

The combined resistance R of two resistors R_1 and R_2(R_1,R_2>0) is given by 1/R=1/R_1+1/R_2 . If R_1+R_2=C (a constant), show that the maximum resistance R is obtained by choosing R_1=R_2 .

Three resistors R_1, R_2, R_3 are to be combined as shown in the figure. Which combination has lowest resistance. Arrive at the expression for the effective resistance of this combination
