Think of it in terms of a central heating system that uses a number of radiators: the water pump applies pressure across all the radiators. But there must also be a pressure difference across the inlet and outlet to each radiator, or water wouldn't flow through the individual radiators. The sum of these pressure differences will equal the pressure delivered across the entire system by the pump.
Now imagine a number of resistances connected in series. There must be individual potential differences across each resistance or current wouldn't flow through them. We call these individual potential differences, 'voltage drops', and the sum of the voltage drops across each resistance will equal the magnitude of supply voltage, but act in the opposite sense.

∙ 14y agoThe cause of voltage drop is when the impedance of connectors is small relative to the components in a circuit. Ex. Air conditioner has 10 ohm resistance and the wire being used has 0.2 ohm resistance, about 2% total resistance of the circuit. The 2% of the supplied voltage is being lost by the wire itself.

∙ 13y agoThe primary cause of excessive voltage drop is excessive resistance, such as a loose connection. It could also be excessive current through a system not designed to carry that current.

Why is voltage split over a series circuit?
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
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).
Why is the voltage drop large in a high voltage transmission line?
The length of the wire causes resistive load to be distributed along line. This accumulated resistance causes the voltage drop.AnswerThe voltage drop along a high-voltage transmission line isn't large in relation to the operating voltage of the line. One of the advantages (there are many) of using high voltages is that, for a given load, the line current is relatively low -so the voltage drop along the line is also relatively low.
What causes sudden voltage drop in houses incase of ac?
Often, this is due to a sudden increase in the load current due, for example, to the the starting current of a motor which has been switched on -this causes a temporary increase in the voltage drop along the line, which is often noticed when the lights in a property temporarily dim. Other causes could be due to external sources, such as a neighbour operating welding equipment.
Why is voltage split over a series circuit?
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
What causes a chiller voltage to drop from 480 volts to 440 volts?
the use and consistency of the use
How does internal resistance affect operation of a cell or battery?
It causes the battery's voltage to drop when a current is drawn from it.
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 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.
What is the voltage drop using?
Voltage drop is caused by circuit resistance
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
Why is the voltage level not constant in electrical power transmission?
Changes in load causes the load current to change, resulting in changes in voltage drop along conductors. This means that the 'receiving end' voltage will vary.
What is the necessary to know the polarity of voltage drop across a resistance?
Sometimes it isn't.Another AnswerVoltage drops don't have polarity in the sense of a positive or negative charge. The term 'polarity', when applied to voltage drops, describe the sense or the direction in which that voltage drop is acting within the circuit. The rule is that a voltage drop always acts in the opposite direction to the current which causes it. An example of when it's necessary to know the polarity (direction) of a voltage drop is when applying Kirchhoff's Laws or other network theorems to solve a circuit
What causes contact chatter in electrical circuit?
Overload can cause contact chatter. Once the contact closes, the voltage in the circuit collapses and that causes the relay to drop out. At this pint the relay energizes, since the voltage is back. This cycle will continue on.
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 cause the voltage drop in shunt generator when its loaded?
because the voltage likes to drop
