Question

Which makes a larger current: fast-moving electrons or slow-moving electrons? Why is this?

Answer 1

Answer:

Fast moving electrons produce larger current because if electrons move faster, the rate of flow of charge in a given volume will be more

Explanation:

Assuming that there are no collisions between the electrons

Fast moving electrons produce larger currents because the rate of flow of charge which is the rate of change of amount of charge in a given volume will be more as the speed of the electrons is more

As the current is defined as the rate of flow of charge and by the formula it is represented as

I = dQ ÷ dt

where I is the current flowing through it

dQ is the change in amount of charge

dt is the change in time

In case of fast-moving electrons the term dQ ÷ dt will be more and therefore the current will be more

∴ Larger current is produced by fast moving electrons
