NCEES Electrical Engineering

Question 1

On the NCEES PE Electrical exam, Ohm's Law states that the voltage across a resistor equals:

Accepted Answer

V = IR

Answer

Ohm's Law: V = IR, where V is voltage in volts, I is current in amperes, and R is resistance in ohms.

Question 2

In NCEES PE Electrical practice, the power dissipated in a resistor R carrying current I is:

Accepted Answer

P = I²R

Answer

Power dissipated in a resistor is P = I²R, also expressible as P = V²/R or P = VI.

Question 3

For the NCEES PE Electrical exam, Kirchhoff's Voltage Law (KVL) states that:

Accepted Answer

The algebraic sum of voltages around any closed loop equals zero

Answer

KVL: the sum of all voltage rises and drops around any closed loop equals zero, reflecting conservation of energy.

Question 4

In NCEES PE Electrical exams, the impedance of an ideal capacitor C at angular frequency ω is:

Accepted Answer

Z = 1/(jωC)

Answer

Capacitive impedance Z = 1/(jωC): it decreases with increasing frequency, making capacitors act as short circuits at high frequency.

Question 5

On the NCEES PE Electrical exam, the three-phase apparent power for a balanced system is:

Accepted Answer

S = √3 × VL × IL

Answer

Three-phase apparent power S = √3 × VL × IL, where VL and IL are line voltage and line current respectively.
