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

What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is the basic difference between electric spark and electric arc?
the time it duration for the action and voltage drop
Why peak voltage of the load is smaller than the voltage from the transformer output?
The voltage appearing across a load is always smaller than the no-load voltage of any voltage source -e.g. batteries, generators, or transformers. In simple terms this is because all these voltage sources have internal resistance or impedance which results in an internal voltage drop when the source delivers a load current. The resulting voltage, therefore, is always the difference between the no-load voltage and the internal voltage drop. A measure of the difference between a source's no-load and full-load voltage is termed its 'voltage regulation'.
What happens when a the electrical voltage is low?
Appliances at home have designated voltage e.g. 220 V or 110 V. When the voltage is dropped, the appliances try to run at their designated power in kW as usual. To keep the power same, current is increased (P = VI). This increase in current can burn the most delicate part of the appliances if the low voltage is experienced persistently.AnswerA drop in supply voltage results in a drop in the power of appliances. For fixed-resistance devices, a 10% drop in voltage results in approx, 18% drop in power.
What is inherent voltage regulation of an onload tap changer for power transformer?
depending on the amount of the load of transformer as well as the power factor of it, there is a transformer specific voltage drop at its terminals, due to the internal impedances. The on-load tap changer can / will be used to compensate this voltage drop or rise.
The difference in voltage between the two sides of a device is called?
Voltage drop.
What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is potential drop?
There is no difference between potential difference and potential drop. Both terms refer to the difference in voltage (i.e. potential) across a component. Depending on how you look at it, both terms can refer to positive or negative differences, i.e. drop, for instance, can be negative, implying a rise.
What is the potential difference between 2 points in a circuit called?
Voltage drop
What is the basic difference between the symbol E and V in electrical and electronics?
E = Voltage drop V = Voltage
What is the potential difference between two points in a circuit is called?
Voltage drop
What is the difference between KCL and KVL?
KCL calculate current . KVL calculate voltage drop.
What is the basic difference between electric spark and electric arc?
the time it duration for the action and voltage drop
What are the differences between emf and voltage drop?
emf and voltageAnswerElectromotive force is the potential difference created by a source, such as a battery or generator, when it is not connected to a load -in other words, on 'open circuit'.Voltage drop is the potential difference across a load, such as a resistor, which causes current to flow through that load.A voltage drop occurs, internally, in batteries and generators, when they are supplying a load. The battery or generator's terminal voltage, when supplying a load, is its e.m.f. less its internal voltage drop.
Why peak voltage of the load is smaller than the voltage from the transformer output?

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).
Whats the permissible voltage drop in a 240V system?
You shouldn't really have much voltage "drop". If you do, it usually means that there is a poor connection somewhere along your service line or inside wiring. Any significant amount of voltage drop can mean that you are at risk of a fire. On the other hand, line voltage into a house may not actually be 240 VAC. Measure the ACTUAL voltage with everything turned off, then see where it goes when you start turning things back on. The difference between the supplied voltage and the load voltage is the voltage "drop".
