A voltage of 600V can be obtained virtually from
Correct answer: D. transformer
- A. dry battery
- B. nickel-cadmium battery
- C. head & tail of an eel
- D. transformer
Explanation
Transformers are devices that can step up or step down voltages. By using a transformer, it's possible to obtain 600V from a different voltage source.Incorrect options: (a) and (b) Dry and nickel-cadmium batteries typically don't provide voltages as high as 600V. (c) This is a whimsical answer and not a practical source of electrical voltage.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
