Question

difference between voltage and current??

Answer 1

Current is the rate at which electric charge flows past a point in a circuit. Voltage is the electrical force that would drive an electric current between two points.

Definition
Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge.	Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. In other words, voltage is the "energy per unit charge”.
Unit
A or amps or amperage	V or volts or voltage
Relationship
Current is the effect (voltage being the cause). Current cannot flow without Voltage.	Voltage is the cause and current is its effect. Voltage can exist without current.
Measuring Instrument
Ammeter	Voltmeter
SI Unit
1 ampere =1 coulomb/second.	1 volt = 1 joule/coulomb. (V=W/C)
Field created
A magnetic field	An electrostatic field
In series connection
Current is the same through all components connected in series.	Voltage gets distributed over components connected in series.
In a parallel connection
Current gets distributed over components connected in parallel.	Voltages are the same across all components connected in parallel.
