    សុំភាគ 4 បន្តលោកគ្រូ👏។ នៅចំណុច សរុបបន្ទុក ក្រោមៗ លោកគ្រូមិនទាន់បានពន្យល់។ មានចម្ងល់បន្តិច
    1. DB 01-L01 និង និង DB-01-L02 មិចបានយើងចាំបាច់បំបែក link គ្នា ទាំងដែលយើងឃើញថា វាស៊ី អំពែតិចមែនទែន?
    2. DB-01- P01 យើងឃើញថាវាត្រូវការ អំពែខ្ពស់ តើយើងគួរតែបំបែកជា ២ ឡាញបានទេ? (21A)
    3. ឃើញលោកគ្រូថា 1hp =750w តែលោកគ្រូសរសេរ 1.5hp គួរតែ 1500 W តែក្នុង excel លោកគ្រូដាក់តែ 750W? ទៅវិញ
    អរគុណទុកជាមុន👏
