It's when there is a supply with a given voltage, and then a piece of equipment is fed through a long piece of cable so that the voltage supplied at the equpiment is somewhat less. The voltage drop is the amount of reduction caused by the resistance of the cable. Voltage drop should be less than 5% of the nominal voltage, e.g. 12 v for a 240 v system.
What else can I help you with?
Is core loss same as no load loss in transformer?
Yes, that is almost true, apart from a very small copper loss in the primary winding that carries the small magnetising current. The core loss (iron loss) depends on the applied voltage. This loss is measured by the open-circuit test, carried out at the working voltage.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
Why is The voltage across the empty socket is equal to the line voltage?
all the sockets are always connected in parallel,due to this the voltage across each soket is same. when any socket is open then there is no voltage loss..so the votage is same like line voltage.
What is the power loss in watts of a conductor that carries 24Ampere and has voltage drop of 7.2Volts?
Power = voltage times current 7.2 volts * 24 amperes = 172.8 watts
Why transformer power expressed in KVA?
because of its losses i.e iron and copper losses. since iron loss depends on voltage (v)and copper loss depends on current(i).
How the length and thickness of wires could affect the brightness of light bulbs?
Voltage loss. On a long run you will loose some voltage so it is sometimes necessary to increase the wire size to compensate for the voltage loss. This loss of voltage will cause a light to be dim as it is not receiving the correct voltage that is was designed to use.
What is the difference between voltage drop and power loss?
voltage drop is the loss or drop that occured across the element so that voltage gets down and current increases across the element and power loss is like i2r loss and like wastage of power without consuming
Is core loss same as no load loss in transformer?
Yes, that is almost true, apart from a very small copper loss in the primary winding that carries the small magnetising current. The core loss (iron loss) depends on the applied voltage. This loss is measured by the open-circuit test, carried out at the working voltage.
What is the voltage loss over 400 feet?
To answer this question the supply voltage and the amperage of the load must be given.
How much voltage loss with a dimmer switch when used for lights?
The voltage loss from using a dimmer switch varies depending on the type of dimmer and the settings used. In most cases, a standard dimmer switch can introduce a voltage drop of around 5-20% when dimming the lights. This reduction in voltage helps regulate the amount of current flowing to the light fixture, allowing for variable brightness levels.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
Why core loss depends on voltage?
Core loss depends on voltage because it is primarily due to hysteresis and eddy current losses in the magnetic core material. When the voltage increases, it leads to higher magnetic flux density variations within the core material, causing an increase in hysteresis and eddy current losses, thus resulting in higher core losses.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
Electricians have another term for voltage drop in a cable What is it?
the formular notation for voltage drop is Ed Another possible term is "IR loss" meaning the current (I) x resistance (R) loss on the wire part of a circuit
Why is The voltage across the empty socket is equal to the line voltage?
all the sockets are always connected in parallel,due to this the voltage across each soket is same. when any socket is open then there is no voltage loss..so the votage is same like line voltage.
Why do power lines have a high voltage in order to minimize current and heat loss?
Power lines have a high voltage to reduce the amount of current flowing through them, which helps to minimize heat loss and energy waste during the transmission of electricity.
