Explain electrical energy with examples and applications. Explain Electric Power as rate of dissipation of energy. Derive its unit as Joule / sec and call it Watt (W). Derive three forms of equation for Power, P=VI, P=I^2R, P=V^2 / R and their applicability. Discuss that KiloWatt (kW) is commonly used unit since Watt is small unit. Realize that W h is commercial unit of energy used in household electricity bill. Derive that 1 kWh = 3. 6*10^6J. Derive potential energy and kinetic energy for current. From it, derive power. P=VI, P=I^2R, P=V^2 / R.
