1. Cyclotron: Sipai lubawk pakhat hi an Holder in sazai (punishment) a pe a, field bial lai tak(center) atanga tlan tan a kual zau tial tial turin a ti a. Field chu a lai tak atanga ding lam leh vei lam fit 1 vel ve ve ah line hnih a rin tlang pawp a field ko tlang thleng rawk in, field bial chu D pahnih in opposite angin a awm a nih chu.

Hrilhfiahna:
Hrilhfiahna:
Sipai lubawk = positive ion(charge particle)
Holder = A.C apply
D chhung = source free region
D in kar (gap) = Source region
Spiral path = magnetic field
Target = Detector
Cyclotron hmanna thenkhat: Cancer treatment (radiation damage), best source of high-energy beam, proton therapy, etc.
2. Rectifier:
a) Half-wave:- Marble dum leh var hi a in karthlak zel a dahin kan lum a, ti chuan kawng khar pakhat hi lo dang turin a awm a. A dum a rawn kal apiangin a in hawng a, a var alo kal apiangin a in khar a, sir lam ah a luang bo zel a. Ti chuan kawngka lehlam ah chhuak in marble dum chauh chu marble var luan bo hnu zel ah(kar awl awmin) alo luang chhuak ta pheuh pheuh a.

Tichuan marble dum leh var chu a inchhawk in an kawng khar ah chuan an lut ta zar zar a.

Tichuan rawng in ang thap chu kar awl awm miah lovin alo luang chhuak ta zawih zawih a.
Hrilhfiahna:
Marble = A.C. Power supply
Marble dum = Positve half cycle of a.c power
Marble var = Negative hafl cycle of a.c. power (or vice versa)
Kawngkhar = Diode
Kawngkhar in hawng = Forward bias diode
Kawngkhar in khar = Reverse bias diode
Rawng chi khat chauh lo luang chhuak = D.C output
Rectifier hmanna te: A.C atanga D.C a covert na a ni a hmanna a tam khawp mai, Adapter/Eliminators, power radios, televisions, computers, battery chargers, mobile phone chargers, d.c kan mamawhna reng reng kha nimai.
