Voltage drop is caused by resistance. From the equation V=IR the voltage across that resistance can be calculated. For a uniform conductor the resistance is linear with the length R=kx where k is in ohms per foot. For a given current, the voltage drop V=Ikx so the voltage drop per foot is Ik. Voltage drop per foot can be measured, allowing a calculation of voltage drop for very long lengths of conductor such as power transmission lines. This is a reasonable approximation as long as the total voltage drop in transmission is small relative to the supply voltage. If the voltage drop is large, the current will be limited by the total resistance. This implies that long distance transmission lines should be high voltage, because 1 megawatt at 10,000 volts requires 100 amps, while at 100,000 volts it only requires 10 amps. The voltage drop per foot for the same conductor would be 10 times as large at 10 times the current, and the power loss (I*IR) would be 100 times as large.
For alternating current, inductance can be a factor; this implies that relatively low frequency would be preferred.
A 25 foot cord will not cause enough voltage drop to worry about.
No. The total voltage drop around a series circuit, per Kirchhoff's voltage law, is zero. However, it is true that the total voltage drop of all of the components except the battery is equal and opposite to the voltage drop of the battery.AnswerInterestingly, the formal definition of electromotive force is based on Kirchhoff's Voltage Law: 'A source's electromotive force is equal to the sum of all the voltage drops around a closed loop, including the source's internal voltage drop'.Expressed as per the original answer, we could also say; 'The algebraic sum of a circuit's electromotive force and voltage drops, including the source's internal voltage drop, is zero'.
because the voltage likes to 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 amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop

Use a level which is at least a foot long. Hold the level in the horizontal level position, and measure the 1/4" drop from the position of the level which is one foot from the end. If you have a four foot level, and the space to use it, you can easily measure one inch of drop per four feet, which is the same as 1/4" per foot.

Same as any other .25 per foot
The question can't be answered without knowing what the voltage is. That is because the allowed voltage drop is 5% of the supply voltage, so you need to know the supply voltage. Then the wire calculation aims to find out what the minimum size of wire is that produces that voltage drop or less.
Drop per foot doesn't care about length of run, it depends on pipe size. Pipe larger than 2" needs only 1/8" per foot (37.5" fall for 300'), 2" and smaller needs 1/4" per foot (75" fall for 300')
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.............................................
Must also know current load to determine.
