Find the current-referenced sensitivity(output voltage per unit of field per unit of current)of a GaAs-based thin-film Hall transducer with the length of 50μm, the width of 10μm and thickness of 5μm, provided that GaAsis doped to1*10^15cm-3. After placing this Hall transducer inside an energized magnet, the output voltage reached 250mV. Find the value of the magnetic field if the sensing current is 10mA.

A synchronous generator is delivering 35% of the power that is capable of delivering to an infinite bus.

Two balanced three phase loads are connected to a busbar with 10kV line voltage at 50Hz. Load A is 168kVA at cosφ = 0,85 (lagging). Load B is connected in Y and draws a complex phase current ?? = 4,79∠ − 24,5°.

1. Calculate the total active, reactive and apparent power at the busbar.
2. Calculate the combined cosφ at the busbar.

A third balanced load is connected to the busbar.The total power at the busbar is now 288kW, cosφ = 0,87 (inductive).

3. Calculate the complex current in the busbar.

Also a capacitor bank (in Δ) will be installed to the busbar to change the cosφ to 1.

4. Calculate the necessary capacitor value per branch.
