Virtual Oscilloscope to try different waveforms and also to input your own voice.
From the seconds/div calculate the frequency of the wave and double check the value.
What is the formula or relation between time period, frequency, angular frequency?

A small town with a demand of 800 kW of electric power at 220 V is situated 15 km away from an electric plant generating power at 440 V. The resistance of the two wire line carrying power is 0.5 Ohms / km. The town gets power from the line through a 4000-220 V step-down transformer at a sub-station in the town. Estimate the line power loss, voltage drop, power to be supplied by the power plant, power loss percentage, step up transformer configuration
