CFESA ELECTRIC EXAM QUESTIONS
AND CORRECT ANSWERS. VERIFIED
2025/2026.
Voltage - ANS Potential difference or driving force of electrons between two lines
Current - ANS Measured in amps. Movement of electrons through a circuit when a difference
of potential exists.
Direct current (DC) - ANS Circuit electrons flow in only one direction from negative to
positive.
Frequency - ANS (Hertz) number of times the alternating current changes from 0 to its peak
positive then zero to peak negative then back to zero.
Power - ANS Amount of energy used. Determined by voltage, current, and resistance in a
circuit.
Resistance - ANS Impedance or opposition to the flow of current. Measured in Ohms. Every
circuit must have resistance.
