Sample BEE - Bachelor of Electrical Engineering Practice Questions

Try these questions from our free BEE - Bachelor of Electrical Engineering practice tests. The correct answer and an explanation follow each question.

1. An open-circuit test and a short-circuit test are performed on a single-phase transformer. What parameters are primarily determined from these two tests, respectively?

   • A. Copper losses and core losses
   • B. Core losses and copper losses
   • C. Voltage regulation and efficiency
   • D. Equivalent resistance and leakage reactance

Answer: B. Core losses and copper losses

The open-circuit (or no-load) test is performed at rated voltage and primarily determines the core (iron) losses and the shunt branch parameters (magnetizing reactance and core loss resistance). The short-circuit test is performed at a reduced voltage with rated current and primarily determines the full-load copper losses and the series impedance (equivalent resistance and leakage reactance).

Answer: C. Carey-Foster bridge method

The Carey-Foster bridge is a modification of the Wheatstone bridge, often used for accurately measuring medium resistances and for comparing two nearly equal resistances. It is particularly effective in minimizing errors due to lead resistances, making it a suitable choice for precision measurements in the medium resistance range.

Answer: C. 8

A 3-variable Boolean function has 2³ = 8 possible minterms, one for each combination of input values.

Answer: D. Skin Effect

The skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density is largest near the surface of the conductor and decreases with greater depths. This effect becomes more pronounced as the frequency increases, reducing the effective cross-section of the conductor and increasing its AC resistance.
