Well, first of all, voltage is not carried. Voltage is the 'pressure' between the ends of
a circuit that makes charges want to flow. The charge carriers that actually do the
physical flowing are the electrons, with their negative charges. When they flow, we
say that there is 'current' in the conductor.

What is the unit used of resistor?
The ohm. It is how much resistance a component or part of a circuit has to the flow of electrical charge when a voltage is induced across it.
What is the role of voltage in an electrical circuit?
Voltage is related to energy by charge. Power equals voltage times current (amperes), and energy equals voltage times charge (coulombs).An ampere is 1 coulomb of charge moving per second.A watt (power) is 1 joule of work done (or energy transferred) per second.
Does voltage flow in a circuit Explain?
Voltage in an electrical circuit is the rough equivalent of pressure in a water pipe. It causes the electricity to flow. Higher voltage; more flow. The difference is that you can think of pressure applied at a single point, but voltage is always the difference in electrical potential between two points. That's how a bird can stand on a 7,000-volt rural electrical line without harm. The potential difference (voltage) between the line and the ground is 7,000 volts, but the potential difference (voltage) between the bird's two feet is very tiny.
Is current is the rate of electrical flow in a circuit and that votage is the opposition of current flow?
'Electricity' is not a quantity; it's the name of a subject area or topic (just like 'chemistry'). So 'current' describes a flow of charge (not 'electricity'), expressed in amperes. 'Voltage' (potential difference) is responsible for 'driving' current, expressed in volts. 'Resistance' is the circuit's opposition to current, expressed in ohms.
What is voltage unit?
Voltage is "electrical pressure", so to speak, or energy per charge. Volts is joules per coulomb.
What is the unit used of resistor?
The ohm. It is how much resistance a component or part of a circuit has to the flow of electrical charge when a voltage is induced across it.

What the amount of energy in an electrical charge?
zero. Energy is the product of charge and voltage, E=ev. No voltage means no energy in charge.
Is the amount of energy in an electrical charge?
zero. Energy is the product of charge and voltage, E=ev. No voltage means no energy in charge.

What is a holiday test?
It is a non-destructive test carried out on a coating, eg.rubberised waterproofing coating to concrete, where holes through the coating are detected by the formation of an electrical circuit where there is insufficient coating to resist the electrical charge.
What is the function of a cell in an electrical circuit?
it's function is to supply energy(electric)
How can you convert the voltage into milli amps?
Voltage is a property of electrical potential. Amperes (and miliamperes) are the units of electrical current. Even though these are related to each other in a circuit, they are not the same thing, and they cannot be "converted" into each other.Also, these properties are only related through a "load" the circuit provides (the resistance and inductance of the circuit), and make sense only when related to each other this way. If there is current, there will be voltage as well, but if there's only voltage, there will be no current unless there is some resistance as well (even a wire has resistance) - otherwise the circuit is "open" and no charge is flowing.In a simple circuit with a voltage source and resistor:milliamps = voltage*1000/resistance.If your circuit has diodes, capacitors, inductors, etc. it gets much more complicated.

What is the complete path where a charge can flow?
An electrical closed circuit.
