Question 1 | Why it is not possible to measure the drift speed of electrons by timing their travel along a conductor? See answer |
Question 2 | The relationship R = V/I tells us that the resistance of a conductor is directly proportional to the potential difference applied to it. What do you think on this proportion? See answer |
Question 3 | A heavy duty battery of a truck maintains a current of 3 amperes for 24 hours. How much charge flows from the battery during this time? See answer |
Question 4 | While analyzing a circuit, the internal resistance of the source is ignored. Why? See answer |
Question 5 | Under what circumstances, the terminal potential difference of a battery exceeds its emf? See answer |
Question 6 | What is the difference between emf and P.D? See answer |
Question 7 | The loop rule is based on the conservation of energy principle and the junction rule on the conservation of charge. Explain how these are based on these principles? See answer |
Question 8 | Why rise in the temperature of a conductor is accomplanied by a rise in the resistance? See answer |
Question 9 | Does the direction of emf provided by a battery depend on the direction of the current flowing through the battery? See answer |
