problems on combination of resistors

How many types of combination of resistors are there and what are they ?

In the following circuits, (Fig. 3.38), heat produced in the resistor or combination of resistors connected to a 12 V battery will be :

In the following circuits, heat produced in the resistor or combination of resistors connected to a 12 V battery will be

(a) Why does resistance increase in a series combination of resistors ? (b) Why does resistance decrease in a parallel combination of resistors ?

Why is resistance less in parallel combination of resistors ?

Discuss series and parallel combinations of resistors with their salient features.

(a) How does the current divide itself in a parallel combination of resistors ? (b) How does the pd divide itself in a series combination of resistors ?

Electrical current is the flow of charged particles. The electric current flows through a wire the same way as how water moves in a river. The electricity is nothing but the flow of electrons. There are two main combinations of resistors in circuit, that is series and parallel. In the given table, Column I shows different combinations of resistors, Column II shows voltages of different arrangements of resistors and Column III shows currents and voltage division needed or not in different arrangements of resistors. When does the voltage division problem arise?
