`6xx10^17`electrons cross through an area per minute. What is the electric current ?

What is the heating effect of electric current?

What will be the number of electron passing through a heater wire in one minute, if it carries a current of 8A

10,000 alpha particles per minute passing through a straight tube of radius r. what is the resulting electric current?

If a number of electrons pass through the cross-section of a conductor in time t, what is the electric current flowing through it?

10,000 electrons are passing per minute through a tube of radius 1 cm. the resulting current is:

30 coulomb electric charge passes through conducting wire in 10 minutes so ...... A electric current will pass through it.

Therefore are 6xx10^(19) electrons per unit cubic metre of pure semiconductor. What will be the number of holes for this semiconductor of dimension 1 cm xx 1 cm xx 2 cm ?

A charge on electron is 1.6 xx 10^(-19) C. How many electrons will be passing in 2 seconds through a cross-section of a conducting wire carrying 0.7 A electric current ?
