Obtaining IV Characteristics for Electrical Components: Equipment, Procedure, and Typical Graphs

The video tutorial explains how to obtain IV characteristics for a resistor, bulb, and diode. It covers the necessary equipment, circuit setup, and step-by-step procedure for conducting the experiment. The tutorial also discusses how to analyze the results by plotting graphs and understanding the behavior of each component. Key concepts include the relationship between current and potential difference, and how resistance varies with different components.

What is the purpose of reversing the battery connections during the experiment?

• To measure the resistance

• To increase the current flow

• To decrease the potential difference

• To investigate current flow in both directions

What is the role of the variable resistor in the experiment?

• To measure the current

• To change the potential difference across the component

• To switch the circuit on and off

• To measure the potential difference

Why is it important to use the same component throughout the experiment?

• To reduce costs

• To save time

• To increase the potential difference

• To ensure consistent results

What does a straight line graph for a resistor indicate?

• The current is inversely proportional to the potential difference

• The current is directly proportional to the potential difference

• The resistance is variable

• The potential difference is constant

How does the diode behave when the potential difference is negative?

• It allows current to flow easily

• It has a very high resistance

• It decreases the potential difference

• It increases the current
