## Why are flashlights connected in series?

They are connected in series because in series the voltage that supplies the flashlight cell increases. Therefore, as the voltage across the flashlight cell increases the brightness is increases. But in parallel, the voltage is the same but the current flows to the flashlight cell increases.

## What is the advantage of connecting cell in series?

Cells connected in series give a greater resultant voltage than individual cells. Voltage increases if the number of cells increases. Series circuits do not overheat easily.

## What is the advantage of connecting batteries in series?

Connecting batteries in series increases voltage, but does not increase overall amp-hour capacity. All batteries in a series bank must have the same amp-hour rating. Connecting batteries in parallel increases total current capacity by decreasing total resistance, and it also increases overall amp-hour capacity.

## What are the advantages of parallel connection?

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.

## Why would some flashlights have more than one battery connected end to end in series?

In effect, the battery “burns” zinc to obtain the energy needed to pump electrons from the negative to the positive terminal. Often two batteries are connected together in series, so that the positive terminal of one battery touches the negative terminal of the other.

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.

## What is the disadvantages of series connection?

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*.

## What is the advantage of parallel connection over series connection?

Advantages of parallel combination over series combination are: 1) In parallel combination each appliance gets the full voltage. 2) If one appliance is switched on/of others are not affected. 3) The parallel circuit divide the current through the appliances.

## What is the difference between connecting batteries in series and parallel?

Batteries connected in series stack their voltages in order to run machinery that requires higher voltage amounts. … In contrast, batteries connected in a parallel configuration are able to increase the amp-hour capacity of your batteries, at the same voltage.

## What is difference between series and parallel connection?

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. … In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.
