nomor 1 dan 2 tolong dijawab yaa pakai caranya besok dikumpul makasiii

1 . diketahui
R = 100 ohm
I = 0,5 a

P = V x I

V = I x R
V = 100 × 0.5
V = 50volt

P = V× I
= 50 x 0.5
= 25 watt (a)


2. diket
V = 10 v
R = 50 ohm


P = V x I

I = V/R
I = 10/50
I = 0,5 a

P = V × I
P = 10 x 0.5
P = 5 watt (b)
