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?
Answer: Brown, Black, Orange
