ÖRNEK: ONDALIK ÖNÇARPAN VE ONDALIK ÖNEKLERİ KULLANARAK AŞŞAĞIDAKİ DEĞERLERİ GÖSTERİNİZ.

a)      60,000 V           b) 350,000 Ω           c) 0,000045 A          d) 150,000 V

Çözüm:

a)      60,000 V = 60x10³ V = 60 kV

b)      350,000 Ω = 350x10³ Ω = 350 kΩ

c)       0,000045 A = 45x10^-6 A = 45 ϻA

d)      150,000 V = 150x10³ V = 150 kV
