- Provide your complete solution and formula. Sample Problem: [EE Board April 2003 ] An alternating current of rectangular wave shape has amplitude of 10 and a frequency of one (1). What is the RMS current?7 Find the average and effective values of voltage for sinusoidal waveform shown in Figure. Vm = 100 V 2x x14 9714 [Ans: 27.17 V, 47. 67 V]a) We assume that the switch is on. Calculate the reactance values and find the charging current in the circuit below. Is the circuit capacitive or inductive? Show that the voltage across the capacitance can be slightly larger than the source voltage U. (This is called the Ferranti effect and means that we can get a voltage rise beyond overhead lines with small loads. This is mostly relevant at the highest voltage levels. The frequency f is 50Hz, and assume voltage U= √2⋅24kV
