Multiple Choice

How would you describe the relationship (resistance) between current and voltage in a filament bulb?

• The resistance of a bulb decreases as the temperature of the metal filament decreases.

• The resistance of a bulb increases as the temperature of the metal filament increases.

Multiple Choice

How would you describe the relationship (resistance) between current and voltage in a resistor?

• The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it.

• The current flowing through a resistor at a constant temperature increases as the potential difference across it increases.

• The current flowing through a resistor at a constant temperature decreases as the potential difference across it decreases.

Multiple Choice
