EXAM QUESTIONS
Question 1
What is current flow?
A. Movement of protons in a circuit
B. Voltage drop across a resistor
C. Resistance to electron motion
D. The flow of electrons in a circuit ✅
Rationale:
Current is the flow of electrons through a conductor, measured in amperes.
Question 2
What is impedance?
