Correct answer
B. capacitance
Explanation
Farad, unit of electrical capacitance (ability to hold an electric charge), in the metre–kilogram–second system of physical units, named in honour of the English scientist Michael Faraday. The capacitance of a capacitor is one farad when one coulomb of electricity changes the potential between the plates by one volt.
Correct answer
D. 40 W lamp will glow brighter
Explanation
The correct answer is 40 W lamp will glow brighter.
Correct answer
D. 600
Explanation
1 Ampere current means flowing of 1 Coulomb charge per second. That means 10 A current in 1 minute or 60 seconds implies 10 × 60 = 600 coulombs.
