ADVANTAGES AND DISADVANTAGES OF SERIES CIRCUITSADVANTAGES AND DISADVANTAGES OF SERIES AND PARALLEL CIRCUITS

The advantages of a series circuit is that when more cells are connected in a series,the voltage across the circuit increases and the current also increases.So the bulbs glow brighter.The current that flows through each bulb is the same.That is why the bulbs in a series circuit lights up with equal brightness.If one of the bulbs in series burns out or becomes disconnected,the other bulbs will not light up.This is because the current flows along one path only and when the circuit is broken,the whole circuit becomes incomplete.When more bulbs are connected in a series,the bulbs become dimmer because the electrical energy supplied by the dry cells is shared by more bulbs.

ADVANTAGES AND DISADVANTAGES OF A PARALLEL CIRCUITThe advantage of a parallel circuit is that current can flow through a parallel circuit in two or more paths.When one bulbs burns out,the current cannot flow through that path.However,current can still flow through the other paths and light up the other bulbs.Also,all identical bulbs in a parallel circuit will light up with equal brightness.If more bulbs are added in parallel,the brightness of the bulbs will remain the same.This is because every bulb connected in a parallel will get the same amount of voltage from the dry cells.The only difference is that when more bulbs are connected in a parallel,the quicker the dry cells become weak.In aseries circuit, the same current flows through all the components. The total voltage across the circuit is the sum of the voltages across each component, and the total resistance is the sum of the resistances of each component. In this circuit, V = V1 + V2 + V3 and R = R1 + R2 + R3. An example of a series circuit is a string ofChristmas lights. If any one of thebulbsis missing or burned out, no current will flow and none of the lights will go on. Application of series and parallel circuits in our daily life

An example of a parallel circuit is the wiring system of ahouse. A single electric power source supplies all the lights and appliances with the same voltage. If one of the lights burns out, current can still flow through the rest of the lights andappliances. However, if there is a short circuit, the voltage drops to almost zero, and the entire system goes down.
