ATT Test 3 QUESTIONS AND ANSWERS
2026
1. According to Ohm’s Law, what is the relationship between voltage (V), current (I), and
resistance (R)?
A. V = I / R
B. V = I + R
C. V = R / I
D. V = I * R
Answer: D
Conceptual Explanation: Ohm’s Law states that the voltage across a conductor is directly
proportional to the current flowing through it, with resistance as the constant of
proportionality.
2. Which logic gate outputs high (1) only when all its inputs are high (1)?
A. OR Gate
B. NOT Gate
C. XOR Gate
D. AND Gate
,Answer: D
Conceptual Explanation: An AND gate requires all inputs to be true to produce a true
output.
3. What is the unit of measurement for electrical frequency?
A. Watt
B. Volt
C. Ampere
D. Hertz
Answer: D
Conceptual Explanation: Hertz (Hz) is the standard unit of frequency, representing cycles
per second.
4. In physics, what does Newton’s First Law of Motion describe?
A. Action and reaction
B. Inertia
C. Force equals mass times acceleration
D. Universal gravitation
Answer: B
, Conceptual Explanation: Newton’s First Law, often called the Law of Inertia, states that an
object will remain at rest or in uniform motion unless acted upon by an external force.
5. Which of the following components is used to store electrical energy in an electric field?
A. Resistor
B. Capacitor
C. Diode
D. Inductor
Answer: B
Conceptual Explanation: A capacitor stores energy in an electric field created between
two plates.
6. What is the binary representation of the decimal number 10?
A. 1010
B. 1100
C. 1001
D. 1111
Answer: A
Conceptual Explanation: The decimal number 10 is represented as 1010 in binary (8 + 2).
