Calculate RMS Value, Power Dissipation and Expression Representing Current Flowing In A Circuit

Question

A supply voltage is given by v = 240 sin 314t + 40 sin 942 t + 30 sin 1570t is applied to a circuit comprising a resistance of 12 Ω connected in series with a coil of inductance 9.55 mH.

(i) Derive an expression to represent the current flowing in the circuit.

(ii) Determine the rms value of the current.

(iii) Calculate the power dissipated in the circuit.

All the relevant formulae and equations used in the solutions should be clearly stated.

Use the most appropriate theories and equations used in the solutions should be clearly stated.

Summary

The question belongs to Electrical Engineering and it discusses about calculating the expression to represent the current flowing in a circuit, determine the rms value for the current and calculating power dissipation in the circuit.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
