How much voltage is lost over distance in electrical wiring?
VOltage drop is a function of cable type, size, current, and
length. See the attached calculator link. (Remember that your total
circuit length is twice your run: both conductors count.)
Asked in Electrical Engineering
What happen when voltage drop occur?
Voltage drops (across conductors) reduces the supplied voltage. This means some % of the supplied voltage is actually being lost by the wire itself. Excessive voltage drop will result in unsatisfactory operation of electrical equipment, and represents energy wasted in the wiring system. Voltage drop can also cause damage to electrical motors and other elements in the system.

What causes electrical current to flow?
Electrical pressure, called "electro-motive force" (EMF), is what causes current to flow in an electrical circuit. EMF is measured in volts. Pressure and the quantity of electricity transmitted can be considered analogous to pressure and quantity of water flowing in pipes: the longer the distance, the higher is the pressure (called the "voltage" for electricity) that is necessary to pump the flow of water (called the "flow of electrical charge, which is also known as the "electric current"). That is why, for long distance transmission, high pressure (voltage for electricity) is required, failing which, the current - and therefore the power - will not reach the intended destination. Instead, it will be lost (also called "dissipate") along the way. We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.

What is it called when voltage is lost across a portion of a circuit?
Is voltage drop means lost of voltage?
Voltage drop means reduction of voltage. Additional Answer According to Kirchhoff's Voltage Law, the sum of the voltage drops around any closed loop within a circuit must equal the value of the supply voltage. So, no, a voltage drop is not a 'lost' voltage, as the circuit's supply voltage is accounted for when you add up all the voltage drops (including any internal voltage drop within the source itself).
Can an impedance matching device reduce electrical costs?
An impedance matching device is used to test the resistance, inductive reactant and capacitive reactant in a circuit. If one component did not match the impedance of the conductor, some of the current will be lost by the conductors itself. In conclusion if electricity is lost, the component needs to meet its regular voltage. It consumes more voltage than expected because of the loss. Impedance matching device can actually reduce electrical cost.

Asked in Electrical Engineering
How are step-up transformers used in the transmission of electrical energy?
Step-up transformers used in the transmission of electrical energy increase the voltage going over Transmission Lines (over 100,000 Volts). For a given amount of POWER to be Transmitted, the higher the Voltage, the LOWER the CURRENT. This reduces the amount of Power LOST to the Resistance of the Transmission Lines. Power Lost is calculated by the Formula: POWER Lost = I2 x R, where I=Current and R=Resistance So, the lower the Current (I), the lower the transmission line losses. At the end of the Transmission Path the Voltage is "Stepped Down" to a value usable for the Customer, usually (220 volts for Residential use in the USA).

An atom that has gained or lost electrons and thus carries an electrical charge?
What is the reason why it is better to use high voltage instead of low voltage on long distance?
High voltage reduces the amount of energy lost due to the resistance of the transmission material (conductor), by reducing the current. In other words, increasing voltage reduces current, and lower current means less resistance loss. Voltage and current have an inverse relationship, and later on when the electricity gets closer to the consumer, voltages can be decreased which increases the current. Increased current means higher resistance, and it is resistance that does the work.
What is difference between electronic and electrical?
flow of current through conductor called electrical ( example - copper, aluminum ) flow of current through semi conductor called electronics ( example - silicon, germanium ) Electronics also includes use of vacuum tubes and other technologies that can amplify and/or modulate signals. Electrical circuits lack the ability to amplify or modulate (note: a transformer that steps up voltage is not amplifying as there is power lost that cannot be made up; an electronic amplifier that raises the signal's voltage does not cause loss of power in the output signal as it can take power from its power supply as needed, it may even raise the signal power as well as voltage).
Is voltage established through a resistor or across a resistor?
Current = charge (electrons) flowing through a resistor. Voltage = energy lost across a resistor. Power = energy lost across a resistor per second. So yes you are correct. Current is established through a component, while voltage and power are established across a component. Answer 'Voltage' is a synonym for 'potential difference'. As the name implies, voltage describes the difference in potential between (or 'across') two different points. So voltage is applied ACROSS a resistor. Further to the original answer. voltage is NOT equivalent to 'the energy lost across a resistor', and power is NOT 'established across a resistor' (power is simply a 'rate', nothing more)!

What is an atom that carries an electrical charge because it has gained or lost electrons?
An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.

Why does the voltage measure differently on a multi meter than the calculated voltage?
To get a better understanding you can search and learn more about the terms: AC Theory and Voltage Drop. In summary, when devices are designed and calculations are made we assume a perfect voltage. However, practically when current is transferred through wires along a distance some of the voltage gets lost due to the resistance of the wire. Transformers are used to boost the voltage once a huge voltage drop occurs. due to the expense of installing a transformer per house, devices are designed to work within a range of plus 10% minus 15% of calculated voltage. for example, you may check your laptop charger and you will see that it may except 100 volts to 135 volts input voltage.

What does a resistor do?
A resistor dissipates a definite, calculated, desired amount of electrical energy. Resistor with its resistance would provide a drag to the free flow of electrons. Hence current gets reduced. Resistance: Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire). Resistance can be described by ohms law: Ohms Law: R = V / I (Resistance = Voltage / Current) (resistance measured in ohms) where: Voltage [V]= the energy lost across an component (voltage measured in volts). Current [I] = the charge (electrons) flowing through an component (current measured in Amps). Electrical resistance can be thought of as sticking your hand out a car window. The faster [current] you drive the harder the wind presses [resistance] against you hand and therefore it takes more energy [voltage] to hold your steady. When trying to overcome electrical resistance, the electrical energy lost is turned into heat. This is how the elements of a household stove, toaster, and fan heater work. Because of the vacuum in a light bulb, the electrical energy lost is instead turned into light. It can be seen the electrical resistance plays a large role in modern life. Resistor: The resistor is the most common electronic component and is used to limit and/or control the voltage and current in an electronic circuit. Resistors are carefully manufactured to provide a predetermined value of electrical resistance which may range from 0.1 ohms to 100,000,000 ohms, depending on the application. The physical size of a resistor also varies dependant on the amount of power passing through the resistor, given by: P = V x I (Power = Voltage x Current) (power measured in watts) There are also many types of resistors including: · Variable Resistor - changes resistance when its shaft is rotated (volume knob on a stereo). · Thermistor - changes resistance when the temperature changes (used in a thermostat). · Light Dependant Resistor (LDR) - changes resistance when the lighting changes (used in children's night-lights). Resistor Example: An LED is a small red light (such as the one on the front of most TVs) and requires 2.0 volts and 0.02 amps to operate correctly. If we connected that LED up directly to a 12 volt battery, the voltage would be too high, and too much current would flow… the LED would blow up. We need to use a resistor to limit the voltage and current. But which value of resistance should the have resistor? Uses ohms law: R = V / I = (12.0 - 2.0) / 0.02 = 500 ohms (Note: the voltage across the resistor is the battery voltage minus the voltage we want across the LED) But which value of power should the resistor be capable of handling? P = V x I = (12.0 - 2.0) / 0.02 = 0.2 Watts
