What is the definition of Ohm's Law?
Ohm's Law describes the behavior of magnetic fields in circuits.
Ohm's Law relates frequency and wavelength in electrical signals.
Ohm's Law defines the relationship between voltage, current, and resistance in an electrical circuit.
Ohm's Law states that power is equal to voltage times current.
What are the three main components of Ohm's Law?

How can you calculate the current if the voltage and resistance are known?
I = V / R
I = R / V
I = V * R
I = V + R
What happens to the current if the resistance increases while the voltage remains constant?
The current increases.
The current decreases.
The current remains the same.
The current fluctuates randomly.
How can Ohm's Law be graphically represented?
A power-current (P-I) graph with multiple intersecting lines.
A voltage-current (V-I) graph showing a straight line.
A temperature-voltage (T-V) graph displaying random points.
A resistance-voltage (R-V) graph showing a curved line.
What does the slope of the graph in Ohm's Law represent?
The power consumed by the circuit.
The voltage of the circuit.
The resistance of the circuit.
The current flowing through the circuit.
Can Ohm's Law be applied to AC circuits, and if so, how?
AC circuits cannot use impedance.
Ohm's Law only applies to DC circuits.
Ohm's Law is irrelevant in all electrical circuits.
Yes, Ohm's Law can be applied to AC circuits using impedance.
