A single phase 240 V, 1 kW heater is connected across single phase 240 V, 50 Hz supply through an SCR. For firing angle delay of 90˚, calculate the power absorbed in the heater element.

Consider a solar PV plant with the following specific conditions: Analysis period: 1 year

Measured average solar irradiation intensity in 1 year: 120 kWh/m²

Generator area of the PV plant: 10 m²

Efficiency factor of the PV modules: 15%

Electrical energy actually exported by plant to grid: 110 kWh

Calculate the performance ratio.

A coil having an inductance of 100 mH is magnetically coupled to another coil having an inductance of 900 mH. The coefficient of coupling between the coils is 0.45. Calculate the equivalent inductance if the two coils are connected in series opposing.

Calculate the inductance per meter of a 50 Ω load cable that has an capacitance of 20 pF/m.
