Every component in a series circuit must have a potential difference across its terminals if current is to flow through that component. We call each of these individual potential differences a 'voltage drop', which is actually a bit of a misnomer as it's not really a 'drop' at all; it would be better termed a 'distribution'. The sum of these 'voltage drops' will then equal the supply voltage applied to the entire circuit.

Voltage drops (across conductors) reduces the supplied voltage.

This means some % of the supplied voltage is actually being lost by the wire itself. Excessive voltage drop will result in unsatisfactory operation of electrical equipment, and represents energy wasted in the wiring system. Voltage drop can also cause damage to electrical motors and other elements in the system.

Mathematically, it's the product of the current across a load and the impedance of that particular load. But this insinuates that the voltage drop is caused by the current passing through the load, which isn't really the case. A voltage drop is necessary if current is to pass through a load, in much the same way that a pressure difference is required across every radiator (as well as across ALL the radiators) if water is to pass through them. So, in reality, a voltage drop is the result of the way in which the supply voltage creates a potential gradient across the entire circuit.

due to high resistance flowing through the circuit which is not made for that

In a series circuit why does the largest voltage drop occur across the largest or smallest resistor?

It doesn't. In a series circuit, the largest voltage drop occurs across the largest resistor; the smallest voltage drop occurs across the smallest resistor.


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.


What is the voltage obtained when a capacitor is placed in a dc circuit?

Eventually, the capacitor will charge to approximately the source voltage level. As this occurs, the current in the circuit will drop to near zero.


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 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 drop voltage in xlpe cable is more than PVC cable?

The voltage drop in a wire has nothing to do with the insulation. Voltage drop has to do with the cross sectional area of the wire.


Why is voltage of the battery not equal to the voltage across each bulb in parallel connections?

There are two possible reasons. Firstly, due to the internal resistance of the supply source, there is an internal voltage drop within that source, and this increases as load current increases. In other words, the closed-circuit (load) voltage is always lower than the open-circuit (no-load) voltage. Secondly, a voltage drop always occurs along the conductors between the supply source and the load. Again, the greater the load current, the greater this voltage drop. In a well-designed circuit, these two voltage drops should be insignificant.


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.
