Question

Hitunglah hambatan listrik dan arus listrik dik :a. daya 450 w dan tegangan 200v b.daya 1200w dan tegangan 220v jawab dengan jalan ya ya friend

Answer 1

A.
P = 450
V = 200
I = P/V = 2,25 A
R = V/I = 200/2,25 = 88,89ohm

b.
P = 1200
V = 220
I = P/V = 60/11 = 5,4545 A
R = V/I = 220/ (60/11) = 40.33 ohm
