Answer 2

Explanation:

Given Find the current in a circuit consisting of a coil and a capacitor in series with an A.C source of 110 V (r.m.s.), 60 Hz. The inductance of a coil in 0.80 H and its resistance is  50 ohms .The capacitance of a capacitor is 8 uF

• frequency f = 60 hz
• So e rms = 110 V
• Inductance L = 0.8 h
• Resistance R = 50 ohms
• Capacitor C = 8 μ F
• Bu using the formula X L = 2πfL
•                                            = 2 x 3.14 x 60 x 0.8
•                                           = 301.44 ohm
• By using the formula X c = 1 / 2 π f C
•                                            = 1 / 2 x 3.14 x 60 x 8 x 10^-6
•                                           = 331.74 ohms
• By using the formula Z = √R^2 + (X L – X c)^2
•                                         = √50^2 + (301.44 – 331.74)^2
•                                         = 58.46 ohms
• Now I rms = e rms / Z
•                  = 110 / 58.46
•                   = 1.881 Amps
• Therefore the current in the circuit is 1.881 Amps.
