advantages and disadvantages of resistor in parallel and resistor in series
Answers
Advantages and disadvantages of series connection of resistors:
ADVANTAGES:
1. To control the current in a circuit, series connection is useful. On connecting the resistors in series the total circuit resistance increases and thus the current decreases.
2. Damage of electrical appliance and short circuit can be prevented by connecting the fuse in series with the mains as well as the electrical appliance.
DISADVANTAGES:
3. Series circuits have a single path that connects the electric source to the output devices. These circuits have limited uses because if a fault occurs in one appliance or the circuit breaks, the current does not flow in the circuit and all the other components in the circuit stop working.
4. If the electrical appliances are connected in series, the applied voltage is divided and the appliance cannot give the light efficiently because of less voltage.
Advantages and disadvantages of parallel connection of resistors:
ADVANTAGES:
1. Parallel circuits provide the same voltage to every source and appliance in the circuit, thus all appliances work efficiently.
2. In a parallel circuit if one appliance is fused, the current continues to flow through the others. Hence other appliances continue to work.
3. Even if we have several power sources, the voltage across a parallel circuit will remain the same. This is because the potential difference, which is the source of voltage, is split across the circuit as a whole; so increasing the power will not alter the voltage.
(There are no disadvantages for parallel connection).
