Question

What's the difference between a charge and current?

I've read in a textbook that: "as the charge on an isolated object increases, the potential difference between the object & earth increases".

Though it also said that electric current is the flow of electrical charge.
Would be very grateful if someone explained it simply and clearly, without copying & pasting anything from the internet. :)

Answer 1

current is rate of flow of charge from high potential to low

it is generally considered that earth has zero potential though it is full of many charges as + and - in much quantity

so i think if charge on that isolated body is poditive than i think we should tell that it is st high potential

Answer 2

Electric Charge :-

➡️An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms.

➡️It is a quantity used mainly in electrostatics.

➡️There are two-types of electric charges; positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract.

Electric current :-

➡️Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms.

➡️Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current.

➡️Electrons, the most common charge carriers, are negatively charged.

Yes, whatever you read was correct !

As we know that potential difference is directly proportional to the charge carried by the object, it is genuine to consider that as the charge in an isolated object increases, the potential difference between the object and earth increases.

Moreover, the potential of earth is taken as zero.

Hope it helps!
