Diketahui w = 20.000 J I = 20A t= 20 s ditanya r ? jawab : . W = I×r×I×t w = I^2 ×r× t 20.000 = 20^2 × r × 20 20.000 = 400 × r × 20 20.000= 8000 × r r = 20.000 ÷ 8000 = 2,5 ohm
Verified answer
Diketahui :W = 20.000 J
I = 20 A
t = 20 s
Ditanya :
R = ... ?
Jawab :
R = W ÷ I² x t
R = 20.000 J ÷ 20² A x 20 s
R = 20.000 J ÷ 400 A x 20 s
R = 2,5 Ohm.
w = 20.000 J
I = 20A
t= 20 s
ditanya r ?
jawab :
. W = I×r×I×t
w = I^2 ×r× t
20.000 = 20^2 × r × 20
20.000 = 400 × r × 20
20.000= 8000 × r
r = 20.000 ÷ 8000
= 2,5 ohm
