In series circuit electrons travel only in one path. Here the current will be the same which passes through each resistor. The voltage across resistor in a series connection will be different. In series connection if one resistor is broken or any fault occurs, the entire circuit is turned off. Series circuits do not overheat easily. The design of series circuit is simple compared to parallel circuits.
Some Christmas tree lights can be in series circuits. If one bulb goes off the entire string goes out. The fuse or the breakers will be connected in series to protect the whole wiring from over current. It can be used as a voltage divider. Batteries in a remote are connected in series.
In parallel circuit electrons travel through many branches in it. In this case the voltage remains the same across each resistors in the circuit. Here the current in the circuit is divided among each branches and finally recombines when the branches meet at a common point. A parallel circuit can be formed in many ways, which means resistors can be arranged in different forms. It can be used as a current divider.

Answer:
Explanation:
Series and parallel combination of resistor :-
When two or more resistors are connected in series, the total resistance of the combination is equal to the sum of all individual resistances.
When two or more resistors are connected in series, the same current flows through each resistor.
When a number of resistors are connected in series, the voltage across the combination (i.e, voltage of the battery in the circuit), is equal to the sum of the voltage drop ( or potential difference) across each individual resistor.
