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

## Which connection is best series or parallel?

While series connection is an all or none, parallel circuit connection gives you the opportunity to give the loads and the appliances their individual switch.

Parallel connection offers resistance to the flow of current compared to series connection..

## Which circuit uses more energy?

In my opinion, series circuit saves more power. Example, a LED. One LED consumes 25mA. If you connect 12 LEDs in Series run on 3 volts.

## How do you find resistance in parallel and series?

The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +…

## Is power the same in series and parallel?

The total power is equal to the sum of the power of each component. (This is the same as with series circuits). The same voltage exists across each branch of a parallel circuit and is equal to the source voltage. The current through a parallel branch is inversely proportional to the amount of resistance of the branch.

## Does a battery last longer in a series or parallel circuit?

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 are resistance connected in series and in parallel?

In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.

## How do I calculate resistance?

Rearrange V = IR to solve for resistance: R = V / I (resistance = voltage / current). Plug the values you found into this formula to solve for total resistance. For example, a series circuit is powered by a 12 volt battery, and the current is measured at 8 amps.

## Which will glow brighter in series?

The bulb which dissipates more power will glow brighter. In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness.

## What makes a bulb brighter?

A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb. Typically, the higher the wattage, the higher the lumens, and the more light output.

## Does series or parallel consume more power?

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

## Why is a parallel circuit dangerous?

The equivalent resistance in the parallel connection of resistors decreases thus, more current than one source can produce is obtained. Unless all appliances in parallel have the same voltage, current would flow from one source into the other. This will result in loss of power.

## Why is parallel better than series?

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 is the most cost efficient connection series or parallel?

8. Which is the most cost efficient connection? Explanation: The advantage of series-connections is that they share the supply voltage, hence cheap low voltage appliances may be used.

## Is current constant in parallel?

Current remains constant in series connection and voltage remains constant in parallel connection , current is like water flowing in rivers it always flow in specific path and with constant amount but when some diversion is created it distribute and amount decrease gradually same here with current.

## Which is brighter series or parallel?

When a bulb in a series circuit is unscrewed all bulbs in the circuit go out. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. … Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.

## What are the disadvantages of parallel circuit?

Disadvantages to a Parallel CircuitSeries vs. Parallel Circuits. … Same Voltage Across all Branches. No matter whether you have several power sources or just one, the voltage across a parallel circuit remains the same. … Complex Current Paths. In a parallel circuit, the current from the power source is split across the circuit. … Complex Circuit Loading.

## What is a disadvantage of a series circuit?

Disadvantages of Series Circuits 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*.

## How do you know if its parallel or series?

In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

## What stays the same in a series circuit?

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.

## How do you add resistance in parallel?

The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total: equivalent resistance of resistors in parallel: 1 / R = 1 / R1 + 1 / R2 + 1 / R3 +…

## Which bulb will glow first?

Bulb B will glow first, followed by A & C (simultaneously). A bulb will glow only when a potential difference is created across its terminal. Note that it is the potential difference which matters, not which potential is higher or lower.
