List four precautions which a student should observe while determining the focal length of a given convex lens by obtaining image of a distant object on a screen.
Official answer
The resistance of the resistor is not given in the figure. The figure only shows a voltmeter and an ammeter connected to a circuit with a resistor, but it does not provide any information about the resistance of the resistor.
Marking scheme
- 1.None
Hint
None
Quick oral answer
The resistance of the resistor is not given in the figure. The figure only shows a voltmeter and an ammeter connected to a circuit with a resistor, but it does not provide any information about the resistance of the resistor.
Common mistakes
- 1.assuming the resistance is given in the figure
Analysis and explanation
The figure shows a voltmeter and an ammeter connected to a circuit with a resistor, but it does not provide any information about the resistance of the resistor. Therefore, we cannot determine the resistance of the resistor from the given figure.
