Question 2 of 5
Which of the following is a good conductor of electricity?
Copper allows electric current to flow easily due to its atomic structure.
Question 3 of 5
What is the relationship between voltage (V), current (I), and resistance (R) in a circuit?
This is Ohm's Law: Voltage equals current multiplied by resistance.
Question 4 of 5
What is the function of a resistor in an electrical circuit?
Resistors limit the flow of current, dissipating energy as heat.
