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. If the electrical power of the generator is doubled, determine the maximum value of rotor angle during the swinging of the generator around its new equilibrium position. Draw the corresponding power angle curve.

How can we implement PWM with another processor such as the Intel i7.

what are some methods to achieve PWM with the Arduino?

1.

(a) What is address resolution?

(b) Where does it occur?

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.

Logic is basically human reasoning that tells us if certain proposition or declarative statement is true.

(a)There are five boards of directors (kojo, kofi, menash musah, and mawule) of a School. The board of director kojo owns 10% shares, kofi owns 30% shares, mensah owns 20% shares, musah owns 25% shares and mawule 15% shares of the total shares. For the adoption of the particular policy to be passed in the board’s meeting more than 66% should vote in favour of the policy. The weightage to the votes depend upon the percentage shares owned by the directors. In the board’s room each director has a switch which he turns ON if votes in favour of policy. Design a switching circuit to ring a bell if policy is accepted in the board’s meeting. Only the NAND gates should be used to realize the circuit.
