In a TV tube, the electrons are accelerated from the rear to the front. What is the direction of the current?

The current flows from A to B as shown in the figure. What is the direction of current in circle?

An electron is accelerated from rest to potential V. the final velocity of electron is

In a TV tube the electron are accelerated by a potential difference of 10 kV. Then, their deBroglie wavelength is nearly-

In an X-ray tube if the electrons are accelerated through 140KV then anode current obtained is 30mA. If the whole energy of electrons is converted into heat then the rate of production of heat at anode will be

An electron moves on a straight line path XY as shown. The abcd is a adjacent to the path of electron. What will be the direction of current, if any, induced in the coil?

If one mole of electrons is passing from point P to another point Q on a straight metal wire in time interval of 1 ms, then what will be the magnitude of current in the wire ? What is the direction of current ?

Answer the following questions: You are sitting in a room in which a strong magnetic field is directed from your left towards right: A beam of electrons is directed from front towards you. What would be ·the direction of magnetic force on this beam?

The direction of conventional current is the same as the direction of the electronic current.
