Question

Give advantages and disadvantages of series and parallel connection of resistors.

Answer 1

Hint:The resistors are said to be connected in series if they are connected to the same wire. Also, the resistors are said to be connected in parallel if they are connected across the wire. The voltage remains constant in the parallel circuit and the current remains constant in the series circuit.

Complete answer:
We can say the resistor is connected in series if it is connected to the same wire. Also, the resistor is said to be connected in parallel if it is connected across the wire.

Let’s explain the advantages and disadvantages of series circuit as follows,

Advantages	Disadvantages
We know that the series circuits do not get heated easily. Therefore, any dry or flammable object placed near the series circuit will not catch the fire in case of overheating of the circuit.	We know that in the series circuit, all the appliances are connected one after another. In case if there is any fault or break at one of the appliances, the appliances connected after that will be cut off from the supply.

Let’s explain the advantages and disadvantages of parallel circuit as follows,

Advantages	Disadvantages
We know that the voltage remains constant in the parallel connection. Therefore, each component in the circuit gets the same amount of voltage.	To construct the parallel connection, we need lots of wires.
We can connect or disconnect a new electric appliance in the circuit without affecting the other components in the circuit.	We cannot meet the requirement when the exact same amount of current is required to pass through the element.
If there is a fault in one of the electric appliances, the current is able to pass through different paths of the circuit.	In parallel circuits, we cannot increase the voltage since the resistance decreases in the parallel circuit.

Note: Even if there are advantages and disadvantages of series and parallel connection of electric circuits, both the connections are equally important and essential. The household appliances are generally connected in parallel across the live wire and the neutral wire.
