Let me explain the concept of a voltage drop and let us forget the lamp for now. Voltage drop is the result of an electrical current flowing through an resistance.
Ohms Law state that:
V = I x R
R = Resistance in ohms
I = Electrical current in ampere
V = Potential difference in voltage or in our example we can call it the voltage drop
Regardless of where a resistance is found in an electric circuit. The product of its resistance and the current flowing through it will results in a voltage drop across the resistance.
If I have a 22ohm resistor in a circuit and on any given instant a 2 ampere current is flowing through it. The voltage across the resistor is 44V. Thus 44V is the voltage drop regardless of what the supply voltage is.
But not only resistors has resistance, in fact all electrical components have some form of resistance even the conductors, cables, connectors and switches.
Other common examples of resistances are:
*Internal resistance of batteries
*Light bulbs
*Electric motors
*Electromagnets
They all have resistance, any conductor or semiconductor what is practically used will have a resistance to it and can therefore have a voltage drop if electrical current flow through it.
The methods used in this example should never be attempted in AC circuits because the effects of magnetic fields and electric field may produce different results. Pure resistance only apply to DC circuits. Sufficient inductive and capacitive reactances especially in equilibrium may produce dangerous voltages in AC circuits.

What is the voltage drop using?
Voltage drop is caused by circuit resistance
What is the voltage drop running through the parallel potion of the circuit?
A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same
What is Voltage rise?
Voltage Rise : The energy added to a circuit. Voltage drop: The energy removed from the circuit.
The resistor in an R-L series circuit has a voltage drop of 53V and the inductor has a voltage drop of 28V what is the applied voltage of the circuit?
The applied voltage is 53+28 = 81V.
What will be the voltage drop when diode and resistance are used in series in a circuit?
voltage drop deviding accure
When Checking voltage at different points in a circuit is what?
Looking for a voltage drop.
What is the voltage drop of a series circuit with four voltage drops of 30 volts?
there is 120V across the circuit.
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 is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
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.............................................
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.
What happens to the current in a circuit as a capacitor charges?
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.
