Current Vs Voltage | Electricity

Показать описание
In this animated lecture, I will teach you about current and voltage in physics.

Q: What is current?
Ans: The amount of charges flow through a unit area in one second is called current. For example, consider a point X on a wire. Let we observe the flow of charges through this point X in one second. Let 5 coulombs charges flow through point X in 1 second. So, the current through point X is 5  amperes.
Remember that the S.I unit of current is Ampere.
The formula of current is " Current is equal to charges upon time".

Q: What is voltage?
Ans: The difference in potential energy per unit of charges between two points is called voltage. For example, Voltage is the electrical energy that is used to light a bulb, run a fan or run a motor, produce a sound in loudspeakers, generate heat in electric heater, etc.
Voltage is produced when charges moves from higher potential point to lower potential point. The S.I unit of voltage is volt.

To learn all these questions, watch this lecture till the end.

I have been so confused about the difference between each of them and what voltage exactly was. Thank you for making me understand what each of them is.

Electrons flow from minus to plus region. In your video (8:23), it is reversed. It goes from minus side and through the bulb and then into the plus side. What your figure is showing is the conventional flow of current (hole current).
