Ohms law trivia quiz questions with answers
Who developed Ohm's Law?
Answer: Georg Simon Ohm.
What is Ohm's Law?
Answer: Ohm's Law is a fundamental law of physics that states that the
current through a conductor between two points is directly proportional to
the voltage across the two points, provided the temperature and other
physical conditions remain constant.
What is the unit of resistance?
Answer: Ohm (Ω).
What is the unit of current?
Answer: Ampere (A).
What is the unit of voltage?
Answer: Volt (V).
What is the mathematical formula for Ohm's Law?
Answer: V = IR, where V is voltage, I is current, and R is resistance.
What is the difference between a series and parallel
circuit?
Answer: In a series circuit, the components are connected in a single path,
whereas in a parallel circuit, the components are connected in multiple
paths.
How is resistance calculated in a series circuit?
Answer: The total resistance in a series circuit is calculated by adding up
the individual resistances.
How is resistance calculated in a parallel circuit?
Answer: The reciprocal of the total resistance in a parallel circuit is
equal to the sum of the reciprocals of the individual resistances.
What happens to current in a circuit when resistance is
increased?
Answer: When resistance is increased in a circuit, the current decreases.
What happens to current in a circuit when voltage is
increased?
Answer: When voltage is increased in a circuit, the current increases.
What happens to voltage in a circuit when resistance is
increased?
Answer: When resistance is increased in a circuit, the voltage increases.
What happens to voltage in a circuit when current is
increased?
Answer: When current is increased in a circuit, the voltage increases.
What is the power formula in terms of current and
resistance?
Answer: P = I^2R, where P is power, I is current, and R is resistance.
What is the power formula in terms of voltage and
resistance?
Answer: P = V^2/R, where P is power, V is voltage, and R is resistance.
What is the power formula in terms of current and
voltage?
Answer: P = IV, where P is power, I is current, and V is voltage.
What is the unit of power?
Answer: Watt (W).
What is the relationship between power and energy?
Answer: Power is the rate at which energy is transferred or used, so energy
is equal to power multiplied by time.
What is the unit of energy?
Answer: Joule (J).
What is the relationship between current and resistance
in a circuit?
Answer: Current is inversely proportional to resistance, so as resistance
increases, current decreases.
What is the relationship between voltage and current in
a circuit?
Answer: Voltage is directly proportional to current, so as current
increases, voltage increases.
What is the relationship between voltage and resistance
in a circuit?
Answer: Voltage is directly proportional to resistance, so as resistance
increases, voltage increases.
What is a resistor?
Answer: A resistor is an electronic component that restricts the flow of
current in a circuit.
What is the color code for a 10 ohm resistor?
Answer: Brown, Black, Black, Gold.
What is the color code for a 100 ohm resistor?
Answer: Brown, Black, Brown, Gold.
What is the color code for a 1k ohm resistor?
Answer: Brown, Black, Red, Gold.
What is the color code for a 10k ohm resistor?
