electronic wishaya samaga danata katayuthu karana ayatanam godak wadagath wena deyak gana thamai me kiyanna yanne.
eeka thamai transistor tester eka. me transistor tester eke thiyena wadagathkama thamai multi meter eken transistor check karanna danne nathi ayata mema circuit eka baawithaaa karala transistor check karaganna puluwan kama.

transistor warga 2k thiyenawa PNP haa NPN kiyala. mema transistor check karanna thiyenne wenas widiyata. eeth ithin electronic walata aluth keneknam tika dawasak yanakam ooka patalena nisaa me podi circuit eka hadaaganna.

podi eethalayakin lakunu karala thiyena thana test karana transistor eka anuwa maaru karaganna .
a kiwwe PNP transistor ekak check karanawanam PNP lakunu kara paththata wayar eka sambanda karanna . NPN ekaknam NPN lakunu kara paththata sambanda karanna.
