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.

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).

Exactly. When moving electrons (current) passes through a resistor, they lose energy. For instance, the light of bulb is due to the energy lost by the electrons. 😊😊😊❤🖐

Sir you said the electric potential difference is known as a volt means the difference b/w two points but the example you have given is one battery that possesses 1.5 volts what does it mean you said two points difference but in that example, you are talking about the difference between positive and negative charge which are in Same conductor how sir?

There are two types of current. Conventional Current: it flows from positive to negative terminal. Electronic Current: it flows from negative to positive terminal. Q: Which one is right? Ans: Electronic current. Q: Why we study conventional current? Ans: As an old convention in Physics which was later proved wrong. 🙌🙌🙌❤

Is it charges or electrons ? If we could visualise how it's flowing in Circuit. It's easy to understand potential differences but in Circuit how it works. Like is negative high p.d. or positive high p.d. How is the direction of current different from charges ?

@justgremoryy2148 4 ай бұрын

Charges is not a physical thing, it's a property of matter. The electrons have negative charge. The current moves from positive to negative while the electrons move from negative to postive
