RUMUS DASAR LISTRIK
● V = I x R ( Volt ).
● P ( 1 phasa ) = V x I x cos φ = I² x R x cos φ ( Watt ).
● P ( 3 phasa ) =√3 x VL x IL x cos φ ( Watt ).
Keterangan :
● V = Tegangan ( Volt ) Æ misal : 220 volt.
● I = Arus ( Ampere ).
●R = Resistance ( Ohm ).
● P = Daya ( Watt ).
● VL = Tegangan antar phasa ( volt ) Æ misal : 380 volt.
● IL = Arus Line ( Ampere ).
