Omggg :( Determining voltage between point a and b given R = 40 ohms
This is what I did for part A:1) ΔVrms = Vmax(1/√2)
ΔVrms = (145)(0.707)
ΔVrms= 102.53
2) Ztotal = √[R² + (XL - XC)²]
XL = 2πfL
XL = 2π(40)(185 x 10^-3)
XL = 46.49
XC = 1/2πfC
XC = 1/[2π(40)(65 x 10^-6)
XC = 1/0.016336382
XC = 61.21
Ztotal = √[40² + (46.49 - 61.2)²]
Ztotal = √(1600 + 216.67)
Ztotal= √(1816.67)
Ztotal = 42.62
3) ΔVrms = (Irms)(Zab)
ΔVrms = (ΔVrms/Ztotal)(Zab)
ΔVrms = (102.53/42.62)(40)
ΔVrms = (2.405)(40)
ΔVrms = 96.2 V
