Voltage is the electrical potential that is produced by a given source (ie, a battery or a generator). The voltage is not changed by the type or number of loads on a circuit. A voltage regulator and/or transformer may change the voltage within a perticular load, but cannot change the complete circuit voltage.

Can electricity flow through a parallel circuit?
'Electricity' is the name given to a branch of science; it is NOT a quantity. So your question should read, 'How does an electric current flow through a parallel circuit?'The answer is that a parallel circuit is made up of two or more individual 'branches'. The sum of the currents flowing through each branch is the value of the current being drawn from the supply by the complete circuit.
Which is the best describes a parallel circuit?
A parallel circuit has more than one resistor (anything that uses electricity to do work) and gets its name from having multiple (parallel) paths to move along . Charges can move through any of several paths. If one of the items in the circuit is broken then no charge will move through that path, but other paths will continue to have charges flow through them. Parallel circuits are found in most household electrical wiring. This is done so that lights don't stop working just because you turned your TV off.Below is an animation of a parallel circuit where electrical energy is shown as gravitational potential energy (GPE). The greater the change in height, the more energy is used or the more work is done.The following rules apply to a parallel circuit:The potential drops of each branch equals the potential rise of the source.The total current is equal to the sum of the currents in the branches.The inverse of the total resistance of the circuit (also called effective resistance) is equal to the sum of the inverses of the individual resistances. One important thing to notice from this last equation is that the more branches you add to a parallel circuit (the more things you plug in) the lower the total resistance becomes. Remember that as the total resistance decreases, the total current increases. So, the more things you plug in, the more current has to flow through the wiring in the wall. That's why plugging too many things in to one electrical outlet can create a real fire hazard.
What happens to voltage in a series circuit?
Total voltage = the source. The voltage around the circuit is divided proportionally by each of the resistances in line. The current is = the source voltage divided by the sum of all the resistance.
In parallel circuit whathappens to the total resistance if one branch opens-Provide an example?
In a parallel circuit, each load added subtracts from total resistance. When one or more loads is removed from a parallel circuit, the total resistance is increased, reducing the total amperage draw. The less resistance a load has, the more current can pass through. This is part of Ohm's law. The mathematical equation that describes Ohm's law is: I=V/R , where I is the current in amperes, V is the potential difference in volts,and R is a circuit parameter called the resistance For example : The humble light-bulb is rated by the watts it uses. The amount of watts used by a light-bulb is calculated using Ohm's law. With the resistance of the bulb's filament and the voltage the bulb is designed to operate with, one can derive the amperage the bulb will draw. The amperage is then multiplied by the voltage to show wattage. Using Ohm's law : With the resistance of a 40watt 120volt light-bulb, only 0.33amps is able to pass through the bulb's 363ohm filament at 120volts. A lamp that has two 40watt bulbs inplace, and the two bulbs are in parallel, the circuit will have a resistance of 179ohms and draw 0.67amps which is 80watts at 120volts.
Why does voltmeter measure current more accurately than an ammeter?
A voltmeter does not measure current, it measures voltage in units named volts. An ammeter measures current in units named amperes or amps in common shorthand. A voltmeter is connected in parallel to the circuit being measured, whereas an ammeter is connected in series with the circuit being measured.
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
How much voltage does each branch of a parallel circuit?
Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)
What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
What is the same in each branch of a parallel circuit?
In a parallel circuit, the voltage across each branch is the same.
Is voltage the same in parallel circuits?
No, voltage is not the same in parallel circuits. Voltage is constant across components in a series circuit, but in a parallel circuit, each component has the same voltage as the power source.
Why a voltage only in parallel?
Depends on what circuit you're refering to, a parallel circuit has parallel lines because it allows for voltage to pass through the circuit, giving more power.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
What happens in a parallel circuit when one battery is added?
When a battery is added to a parallel circuit, the total voltage in the circuit increases as the new battery adds its voltage to the existing voltage sources. The total current in the circuit may also increase as the additional voltage motivates the charges to flow through the parallel branches of the circuit.
In a parallel circuit the is the same for every leg in the circuit?
voltage
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
Why does the same voltage run through all the branches of a parallel circuit irrelevant of the different resistance appliances on those branches?
The same voltage is present but does not run. It is the current that could be described as "runniing" through the different branches. Just by definition, parallel circuits necessarily have the same voltage. It is architecture of the circuit.
What is same in the parallel circuit?
the term voltage is constant in parallel circuits
