Question 1 of 5
What is the relationship between voltage (V), current (I), and resistance (R) in a circuit?
Ohm's Law states that Voltage (V) is equal to Current (I) multiplied by Resistance (R).
Question 2 of 5
In a simple circuit with a resistor, what happens to the electrical energy?
The resistor converts electrical energy into heat (energy loss).
Question 3 of 5
What happens to the voltage across a resistor when current flows through it?
A voltage difference, or 'drop', occurs across a resistor as current flows.
Question 4 of 5
Which formula correctly represents the power (P) dissipated by a resistor?
Power can be calculated using multiple formulas based on Ohm's Law and the relationship between voltage, current and resistance.
Question 5 of 5
What is the unit of measurement for electrical resistance?
Electrical resistance is measured in Ohms (?).
