(i) The procedure of ejection of electrons from a metal surface by the application of heat is known as thermionic emission and emitted electrons are known as thermions and current flowing is known as thermion current.
(ii)Thermions have dissimilar velocities.
(iii)This was discovered by Edison
Vgs= -1.5 v Idss= 10 mA Vp = - 4 v Ids = ? Vds = ?
The electric field strength, defined as a force per unit charge, has the units Newton per coulomb, N/C. The formula for electric potential difference, ΔV = Ed, though, suggest
