Assertion Reason Questions on Electricity: Circuits and their Components
Assertion Reason Questions
Q1. Assertion (A): A lamp glows only when the electrical circuit is complete.
Reason (R): A complete circuit provides a path for electric current to flow from the cell’s positive terminal to the negative terminal.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Electric current needs a closed circuit to flow and light the lamp.
Difficulty Level: Moderate
Q2. Assertion (A): An LED glows only when connected in the correct direction in a circuit.
Reason (R): The current can flow through an LED in both directions.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: LEDs are unidirectional and glow only when correctly aligned with current flow.
Difficulty Level: Moderate to Tough
Q3. Assertion (A): Electric switches can be placed at any point in a circuit to control the flow of current.
Reason (R): A switch functions by either completing or breaking the electrical circuit.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: The position of the switch doesn’t affect its function — it controls continuity.
Difficulty Level: Moderate
Q4. Assertion (A): Metal wires are used to connect electrical components in circuits.
Reason (R): Metals are good conductors of electricity and allow electric current to pass through them easily.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: The high conductivity of metals like copper and aluminium makes them ideal for wires.
Difficulty Level: Moderate
Q5. Assertion (A): The filament of an incandescent lamp glows when current passes through it.
Reason (R): The filament is a thick metal strip that reflects light from external sources.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: The filament glows because of the heat generated by current, not because it reflects light.
Difficulty Level: Tough

Frequently Asked Questions (FAQs) on Electricity: Circuits and their Components Assertion Reason Questions
Q1: What are Assertion-Reason questions in Class 7 Science?
A1: Assertion-Reason questions consist of two statements: an Assertion (A) and a Reason (R). Students must determine whether both statements are true and if the reason correctly explains the assertion.
Q2: How do I answer Assertion-Reason questions correctly?
A2: To answer correctly, follow these steps:
Check if both statements are true.
If both are true, see if the reason logically explains the assertion.
Use the standard answer choices (Both true with explanation, Both true without explanation, A true but R false, A false but R true).
Q3: What is the new Science textbook “Curiosity” for Grade 7 about?
A3: The new textbook “Curiosity” for Grade 7 Science introduces students to the world of scientific exploration and discovery. It focuses on fostering curiosity and encouraging students to ask questions, observe the world around them, and engage in hands-on activities to understand scientific concepts.
Q4: What is the best way to prepare for Assertion-Reason questions?
A4: Strengthen your understanding of concepts by studying NCERT books.
Focus on cause-effect relationships in science topics.
Practice Assertion-Reason questions regularly from worksheets, sample papers, and past exams.
