Can we say that potential difference is potential energy difference per unit charge. when positive charges move from higher potential to lower potential does their potential energy decrease . And when they they pass through battery does the potential energy per unit charge decrease.Can we...

I am a bit confused whether electron passes through a battery or no. My book says battery pumps electrons so it should be the case am I right?

Thanks now I am able to interpret. Can we say that after battery creates a potential diiference, electron gains potential energy as it passes through it and the difference in potential energy per unit charge between two pointsis called voltage between the two points. Am I right?

What do we mean when we say that voltage drops across a resistor?and what does it mean when we say that a point is at lower potential as compared to some other point?Can we say that potential is potential energy per unit charge?

Please help me. I am not understanding, these statements are directly said by people and written in books tried a lot to find out their meaning. .What do they mean when they say we apply a potential difference. There should be an electric field right to move charges how and where is it directed...

In a simple circuit with battery connected to a resistor or a combination of resistors where is the electric field directed . What do we mean when we say battery creates a potential difference between two points in a conductor? And by the statement that battery moves positive charge from low...

thanks

yeah, me too thanks

Here in the lower left corner its given that force is change in momentum upon time. where he writes the change in momentum and divides it by time between two collisions as given above it.

see this

In the derivation of finding pressure exerted by a gas using kinetic theory of gases I am not understanding why the time between two collisions is taken as the time for rate of change of momentum when a particle bounces back from the wall. please help me

What is the significance of the radioactive decay constant?

got it , but can you please tell what will be the wavefront for converging and diverging rays and why?

why does a point source produce spherical wavefront because waves are emitted in all the directions in 3 dimension

like if we through a stone in water the wavefront of water waves will have spherical structure as an example
