arus listrik (I) = 0,25 ampere
waktu (t) = 30 menit
=> 30 x 60
=> 1800 sekon
energi (W) = 36 kj
=> 36 x 1000
=> 36.000 joule
tanya : hambatan (R) ?
jawab:
W = I² x R x t
36.000 j = (0,25)² x R x 1800s
36.000 = 0,0625 x R x 1800
36.000 = 112,5 x R
R = 36.000/112,5
R = 320 ohm
jadi besar hambatannya adalah 320 ohm
