Answer the questions below after watching the video
What does Ohm's Law state about the relationship between current, voltage, and resistance?
Resistance is directly proportional to current
Current is directly proportional to voltage and inversely proportional to resistance
Voltage is directly proportional to resistance
Current is inversely proportional to voltage
How can the resistance (R) be calculated if voltage (V) and current (I) are known?
R = V * I
R = V / I
R = V + I
R = I / V
What is the characteristic of an ohmic conductor regarding its resistance?
Resistance is zero
Resistance increases as voltage increases
Resistance remains constant regardless of voltage
Resistance decreases as voltage increases
In the experiment with a resistor, what was observed when the voltage was increased?
The voltage remained constant
The current decreased
The resistance increased
The current increased proportionally
What does the straight line in a current-voltage plot of a resistor indicate?
Decreasing resistance
Ohmic behavior
Increasing resistance
Non-linear resistance
What unusual behavior does an incandescent light bulb exhibit when tested for resistance?
Resistance increases as the temperature increases
Resistance decreases as the temperature increases
Resistance remains the same at different temperatures
Resistance is not affected by temperature
Why is an incandescent bulb considered a non-ohmic component?
It has a constant resistance
Its resistance changes with applied voltage

Variable power supply
Semiconductor diode
Incandescent light bulb
Standard resistor
What is a key characteristic of a semiconductor diode in terms of current flow?
It conducts only in the forward direction after a certain voltage
It has constant resistance
