Could someone please help me with the below tasks? Thank you!

(b) The following voltage is applied to terminals A and B of the circuit shown below. v =110sinot + 22sin(3cot + 509) + 5.5sin(5cut - 350) Volts. Fundamental frequency = 50Hz 250 100mH C V A B i) Calculate the value of capacitor, C, required to produce resonance at the third harmonic frequency (150Hz) ii) With this value find an expression for the instantaneous current in the circuit. (c) Analyse the following circuits by applying the principles of AC theory to calculate the impedance of the following circuits when connected to a 50Hz sinusoidal ac supply. 100 Ohms L1 R1 1mH C1 1UF V1 240V / 50Hz ii. V1 100 Ohms L1 C1 240V / 50Hz R1 1mH 1UF (d) Make a judgment about the expression generated in b(ii) and apply circuit theory to explain why the second term represents the majority of total current drawn. Then apply circuit theory to explain what happens at resonance in a parallel RLC circuit. (~400 Words)
