Resistors are sometimes joined together and they have several applications in electronics.Draw a series combination of three resistors `R_1,R_2 and R_3`

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 1ohm, 2ohm and 3ohm are combined in series. What is the total resistance of the combination?

Capacitors can be combined to obtain any desired capacitance in an application:- Two capacitors C_1, and C_2 are connected in series. This combination is connected in parallel with a third capacltor C_3 :- Draw a diagram of the above combinatlon.
