1.
a. E = B.L.v = 0,5. 0.1. 1 = 0,05 v = 50 mv
b. I = E/R = 50 mv/20 = 2,5 mA arah kebawah pada kawat L
c. F = B.i.L = 0,5. 2,5.10⁻³ . 0,1 = 0,125.10⁻³ N
2.
a Xc = 1/ωC = 1/2πfC = 1/(2π.60.70.10⁻⁶) = 37,9 Ω
Xl = ω.L = 2π.60. 230.10⁻³ = 86,7 Ω
Impedansi
Z = √ { R² + (Xl - Xc)² }
Z = √{ 200² + (86,7 - 37,9)² } = 205,9 Ω
b.
tan Φ = (Xl - Xc)/R = (86,7-37,9)/200
tan Φ = 0,244
Φ = 13,7⁰
c.
Im = Em/Z = 36/205,9 = 0,17 A
d.
VRmaks = Im. R = 0,17. 200 = 34 v
VLmaks = Im. Xl = 0,17. 86,7 = 14,7 v
VCmaks = Im. Xc = 0,17. 37,9 = 6,4 v
