Listrik Dinamis
1/Rp = 1/R2 + 1/R3
1/Rp = 1/12 + 1/4
1/Rp = 1/12 + 3/12
1/Rp = 1/3
Rp = 3
Rs = R1 + Rp + R4
Rs = 3 + 3 + 2
Rs = 8
E = P . t
E = I² . R . t
E = 2² . 8 . 120
E = 3840 J
mencari hambatan total :
1/Rp = 1/12 + 1/4
1/Rp = 1/12 + 3/12
1/Rp = 4/12
Rp = 3 Ohm
R seri = 3 + 3 + 2
R seri = 8 Ohm
I = 2 A
R = 8 Ohm
t = 2 menit = 120s
energi listrik :
V = I.R
V = 2 × 8
V = 16 V
W = V.I.t
W = 16 × 2 × 120
W = 3.840 J
