# Quick Answer: Which Is The Most Cost Efficient Connection?

## Why is parallel connection preferred over series connection?

When appliances are connected in a parallel arrangement, each of them can be put on and off independently.

This is a feature that is essential in a house’s wiring.

Also, if the appliances were wired in series, the potential difference across each appliance would vary depending on the resistance of the appliance..

## Which is safer series or parallel?

In terms of safety, parallel mods are the way too go, especially if you’re just starting to get into unregulated devices. With all this being said, even though a parallel box is technically safer than a series box.

## What is the disadvantage of parallel circuit?

The disadvantage of a parallel connection becomes apparent with a short circuit, such as when someone jams a wire between the two contacts of an electrical outlet. A short circuit has very low resistance, which in turn causes current in the circuit to increase tremendously, and bang!

## Why current in series is same?

In a series circuit, the current is the same at each resistor. … The voltage drop (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same. Thus the electric potential difference across any one of the bulbs will be the same as that across any one of the other bulbs.

## Does series or parallel give more power?

The power dissipated by each resistor is considerably higher in parallel than when connected in series to the same voltage source.

## Which is more efficient series or parallel?

Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit. Another advantage to the parallel circuit is that if one loop is disconnected, then the other remains powered.

## Which of the following is an example of series connection?

Any switch in your house that controls a single bulb is a series circuit. The switch and bulb are in series. If you have a dimmer switch, the dimmer is in series with the bulb – kinda like a variable resistor – and reduces the voltage/current/brightness of the bulb.

## What’s better series or parallel wiring?

Series – When you wire (hook-up) speakers in Series, the speakers resistance (as measured in ohms) is additive – i.e. putting two 8 ohm speakers in Series results in a 16-ohm load. Parallel – When wiring in parallel, the resistance of the speakers decreases.

## 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.

## Do batteries last longer in parallel or series?

When batteries are hooked up In series, the voltage is increased. For example, two – 6 Volt batteries connected in series produce 12 Volts. When batteries are hooked up in parallel, the voltage remains the same, but the power (or available current) is increased. This means that the batteries would last longer.

## Why do houses use parallel circuits?

Parallel circuits are used in homes because the loads can be operated independently of each other. That means that you can have an electrical item turned on and running without needing to have all of the other loads on and running as well.
