Voltage drop means reduction of voltage.
Additional AnswerAccording 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).
Imagine three central-heating radiators. In order for water to flow through them, you will obviously need a difference in pressure across all three. But for water to flow through each individual radiator, you need a pressure difference between its inlet and outlet. The sum of the pressures across each individual radiator will equal the total pressure across all three radiators.
The pressure difference across all three radiators is equivalent to the electromotive force applied across three resistors (or lamps, or whatever), and the pressure difference across each individual radiator is equivalent to the voltage drop across each individual resistor.
The sum of the voltage drops will equal the electromotive force.

What is it called when voltage is lost across a portion of a circuit?
This is often called a "voltage drop".
How many dB attenuation translates into 75 percent of voltage being lost to attenuation?
100 percent means full voltage or 0 dB.When 75 percent of the voltage is lost you still have 25 percent of the voltage.25 percent means damped to (-)12 dB.
If two resistors have same voltage drop in a series circuit it means?
It means the two resistors have same resistance
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
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).
What is it called when voltage is lost across a portion of a circuit?
This is often called a "voltage drop".
What is volts drop?
the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................
What is IR drop?
IR Drop means voltage drop. As voltage drop across any resistance is product of current (I) passing through resistance and resistance value(R ) , it is often written as IR 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 a IR drop across a resistance?
IR drop across a resistance is voltage. The letter I means current, and the letter R means resistance. Current times resistance, by Ohm's law is voltage.
What is lost volt according to science?
In science, lost volt typically refers to the voltage drop that occurs in a circuit due to resistance. This voltage drop represents the energy lost as heat when current flows through a component with resistance. It is calculated using Ohm's Law, V = I * R, where V is the voltage drop, I is the current, and R is the resistance.
Why resistance drop occurs in a conductor?
All conductors have some amount of resistance associated with them. There is voltage drop along the length of a conductor because the potential energy of the voltage is lost to heat losses (I^2 *R) due to this resistance. The more resistance, the more voltage drop. The current is set at a given voltage and power level.
How many dB attenuation translates into 75 percent of voltage being lost to attenuation?
100 percent means full voltage or 0 dB.When 75 percent of the voltage is lost you still have 25 percent of the voltage.25 percent means damped to (-)12 dB.
Where is the most resistance lost in a series circuit?
Resistance isn't lost. The largest voltage drop will occur across the largest resistance in a series circuit.
What is the decibel loss of a signal that loses half its power during the course of transmission?
When the power (energy) is dropped to the value of 50 percent, the decibel loss is 3 dB, but the voltage is dropped to the value of 70.1 percent. Power drop to 50 % means -3 dB; that is 70.1 % voltage drop. Power drop to 25 % means -6 dB; that is 50 % voltage drop.
If two resistors have same voltage drop in a series circuit it means?
It means the two resistors have same resistance
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".
