Answer:

22.Easy to design and build the circuit. If a component breaks, the current flow stops. It acts as a current regulator. The cost to build a Series Circuit is less compared to Parallel Circuit.

23.The first disadvantage is that, if one component in a series circuit fails, then all the components in the circuit fail because the circuit has been broken. The second disadvantage is that the more components there are in a series circuit, the greater the circuit's resistance*.

24.There is no division of voltage among the appliances when connected in parallel. The potential difference across each appliance is equal to the supplied voltage. The total effective resistance of the circuit can be reduced by connecting electrical appliances in parallel.

25.In parallel circuits, we cannot increase the voltage since the resistance decreases in the parallel circuit.
