## Electric Current and flow of electrons

I have read that the FLOW OF ELECTRONS is called electricity. I wanna know that what is meant by flow of electrons? Pleaz answer me….

Electric current is the flow of charges.

## Potential Difference – misconception

What actually it means when we say “potential difference across..” ? Does it indicate that the somehow the energy level of electrons across it is less than on the other side or is it just the amount of energy consumption across it. If latter is true then in AC we’ve voltages which dont algebraically add [...]

## Dimensions of angle, specific heat, heat, latent heat, frequency, charge, potential difference, resistance.

What are the dimensions of angle,specific heat,heat,latent heat,frequency,charge,potential difference,resistance?

• Angle does not have any dimension as it is a pure ratio
• Dimensions
