Voltage drop
Yes. I think that is a definition of current.
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.
Yes, voltage is a kind of electric pressure. It is also called potential. When there is potential difference between any two points, current starts flowing from high pressure point to low pressure point. FOR EXAMPLE : When there is a difference in air pressure between two regions, air moves from region of low pressure to region of high pressure causing winds In this case air is the potential and wind is electric current
The force that causes electrons to flow is called the Potential Difference, and it is measured in Volts(V).
Voltage drop
The source of electrons in a circuit is supplied by an electric potential difference across two points . This potential difference in a circuit is called as voltage and is measured in joules per coulomb or volts.
The potential difference between the ends of a conductor is called voltage.
Yes. I think that is a definition of current.
It is called power supply or battery.
It is the potential difference between the positive and negative terminals of the battery. The unit of electrical potential is the volt, so the difference in potential between two ponts is also a quantity with units of volts, colloquially called the 'voltage' between the points.

Voltage.The correct term for the amount of energy per unit of charge is potential difference.Energy = Charge * VoltageSimple rearranging gives: Voltage = Energy / ChargeTherefore a volt can be defined as a "joule per coulomb".
A voltmeter measures the difference in potential between two points on a circuit. An ammeter measures the amount of current passing through a point in a circuit. Although you often see them packaged together in a tool called a multimeter, they measure different quantities: Voltage, also known as potential difference, measured in volts, and Current, measured in amperes, or just amps. Also, they're used in somewhat different ways: -- The voltmeter simply touches the two points in the circuit between which the voltage is measured. -- The ammeter has the circuit current flowing through it. That means the circuit must be broken briefly, and the ammeter connected into the 'hole', before the current can be measured. (There are instruments that are exceptions, but they're rather specialized. The statement above holds generally true for the common ammeter.)

Membrane potential
Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.
