Component Characteristics

Question 1

Explain the Graph of the Torch Bulb?

Answer 1

• The Line Curve Away From the Y-Axis. So the Current is Not Directly Proportional to the Potential Difference.
• The Resistance Increases as the Current Increases.
• Reversing the Potential Differences Reverses the Current.

Question 2

Explain the Graph of the The Diode?

Answer 2

• In the Forward Direction, the Line Curves Towards the Y-Axis.
• In the Reverse Direction, the Current is Virtually Zero.

Question 3

Thermistors and Light-Dependent Resistors are Used in ___________ Circuits.

Answer 3
