NCERT Class 10 Science Electricity: In-text questions (page 174) Solutions
AI-written, checked on 23 Oct 2026
Solutions written by Shishya, checked — not the board's official answers
Step-by-step working for every question of In-text questions (page 174) in NCERT's Class 10 Science book, chapter “Electricity”, written by Shishya. Each question is in our own short words; open the NCERT chapter for the exact wording and figures.
How these were checked: the solutions were drafted with AI and then read and corrected on 23 Oct 2026. Every numerical final answer is recomputed from the question's own numbers by a calculator check that runs before each release; proofs and explanations were read, not machine-checked. The NCERT textbook is the authority — if something here disagrees with it, follow the book.
Tap “why?” under a step to see the textbook rule it uses — from Shishya's fixed list of NCERT Class 9-10 rules, not written by AI for this page. A step without one has no rule from the list yet.

In-text (page 174) Q1
Name a device that helps maintain a potential difference across a conductor.
- A device that helps maintain a potential difference across a conductor is a battery.
- A battery consists of one or more electrochemical cells connected in series or parallel.
- It provides a steady voltage to drive current through the circuit.
Answer: A battery (or a cell) helps maintain a potential difference across a conductor.
In-text (page 174) Q2
What does it mean to say the potential difference between two points is 1 V?
- The potential difference between two points is defined as the work done in moving a unit charge from one point to the other.
- When we say the potential difference is 1 volt, it means that 1 joule of work is done.
- This work is performed in moving a charge of 1 coulomb between the two points.
- Thus, 1 V represents the energy consumed per unit charge in moving it across the points.
Answer: It means that 1 joule of work is done in moving a charge of 1 coulomb from one point to the other.
In-text (page 174) Q3
How much energy is given to each coulomb of charge passing through a 6 V battery?
- The potential difference (V) is defined as the work done (W) in moving a unit charge (Q) between two points.
- The formula relating these quantities is V = W ÷ Q.
- We can rearrange this formula to find the energy or work done: W = V × Q.
- The potential difference of the battery is given as 6 V.
- The amount of charge passing through is given as 1 C.
- Substitute the values into the formula: W = 6 V × 1 C.
- Calculate the result: W = 6 J.
Answer: 6 J
