These questions will be both multiple choice and written, focusing on how to use what students have learned in real-life situations.

This article explores Chapter 11: Electricity. It highlights key competency-based questions and provides answers to help students succeed. Prepare for your CBSE Class 10 Science exams with important competency-based questions from Chapter 11: Electricity.

CBSE Class 10 Science Chapter 11: Electricity Important Competency-Based Questions

Q.1 The graph below showsthe variation of resistivity of copper with temperature.

He then heats the copper resistor. What will happen to the current flowing through the circuit? Why?

A. The current will increase because the resistance of copper increases with an increase in temperature.
B. The current will increase because the resistance of copper decreases with an increase in temperature.
C. The current will decrease because the resistance of copper increases with an increase in temperature.
D. The current will decrease because the resistance of copper decreases with an increase in temperature.

Answer. C. The current will decrease because the resistance of copper increases with an increase in temperature.
