Question 1 of 10
What is the formula for calculating voltage (V) using Ohm's Law?
Voltage is directly proportional to current and resistance, hence V = I * R.
Question 2 of 10
What does 'I' represent in Ohm's Law?
I represents the current flowing through the conductor.
Question 3 of 10
What is the formula for calculating resistance (R) using Ohm's Law?
Resistance is calculated by dividing voltage by current, thus R = V / I.
Question 4 of 10
What are the units of measurement for resistance?
Resistance is measured in Ohms (?).
Question 5 of 10
According to Ohm's Law, current is ________ proportional to voltage.
Current is directly proportional to voltage; as voltage increases, so does current.
Question 6 of 10
What happens to the current if the voltage doubles and the resistance remains constant?
According to Ohm's law, doubling the voltage while keeping resistance constant will double the current.
Question 7 of 10
What happens to the current if the resistance doubles and the voltage remains constant?
According to Ohm's law, doubling the resistance while keeping the voltage constant will halve the current.
Question 8 of 10
Which of the following is a limitation of Ohm's Law?
Ohm's Law is only applicable to linear devices.
Question 9 of 10
What is the effect of increasing the temperature on a resistor?
The effect varies depending on the type of resistor; some have positive temperature coefficients, while others have negative coefficients.
Question 10 of 10
Ohm's Law primarily describes the relationship between which electrical quantities?
Ohm's Law defines the relationship between voltage, current, and resistance.
