Question 1: The basic unit for measuring current flow is the:
A. Volt
B. Ohm
C. Ampere
D. Watt
Correct Answer: C. Ampere
Rationale: The ampere (A) is the basic unit for measuring electric
current, which is the flow of electrons through a conductor.
Voltage (volt) is the electrical potential difference, resistance
(ohm) opposes current flow, and wattage measures power.

,Understanding electrical units is fundamental for EEG
instrumentation safety .
Question 2: Impedance can best be described as:
A. Current produced by a wire coil in a magnetic field
B. Resistance to alternating current
C. Ability to store an electrical charge
D. Resistance to direct current
Correct Answer: B. Resistance to alternating current
Rationale: Impedance is the total opposition to alternating
current (AC) and includes both resistance and reactance. In EEG,
low and balanced electrode impedances are critical for
obtaining high-quality recordings with minimal artifact.
Impedances should typically be below 5 kΩ and balanced
between electrodes .

,Question 3: Which describes the action of a capacitor?
A. Opposes changes in current flow
B. Converts alternating current to direct current
C. Creates a direct current resistance
D. Stores electrical energy
Correct Answer: D. Stores electrical energy
Rationale: A capacitor is a passive electronic component that
stores electrical energy in an electric field. In EEG
instrumentation, capacitors are used in filters to block DC signals
while allowing AC signals to pass. They can also be used to
reduce artifact .
Question 4: Which of the following statements about current is
false?
A. Current may be AC or DC
3
, B. Current flows when there is a source of voltage and a
conductive pathway
C. Current is movement of electrons in a conductor
D. Current is measured in coulombs
Correct Answer: D. Current is measured in coulombs
Rationale: Current is measured in amperes (amps), not coulombs.
A coulomb is a unit of electrical charge. Current flow requires a
voltage source and a complete conductive pathway to allow
electron movement. EEG signals are very low-voltage (microvolt
range) signals that must be amplified for interpretation .
Question 5: The input voltage necessary to give a calibration
deflection between 5 and 10 mm when the sensitivity is 30
μV/mm is:
A. 150 μV
