The anode of a thermionic diode is connected to the negative terminal of a battery and the cathode to its positive terminal.Then, No appreciable current will pass through the diode.
Explanation:
Option (a) is correct
- When the anode is allocated a negative potential compared to the cathode, they move the electrons away to the cathode.
- So there is no current going to pass into the diode. therefore the option (a) is right.
Diode:- A diode is an electronic element with 2 electrodes which allows electricity to pass in one path and not in another path.
Electrons:- Any electron is really a stable part of such an atom which is charged negatively. Electrons occur in and around the atomic nucleus.
