Given information:
The product of two decimals is 0.768.
One of the decimal numbers is 1.6.

Finding the other decimal number:
Let the other decimal number be x.

Calculating the product:
1.6 * x = 0.768
x = 0.768 / 1.6
x = 0.48

Therefore, the other decimal number is 0.48. Hence, option 'A' is the correct answe

Corona Effect and Spacing Between Conductors

The corona effect is the phenomenon of ionization of air surrounding a conductor carrying high voltage, leading to the formation of a visible glow and loss of energy. The spacing between conductors plays a crucial role in the occurrence of the corona effect.

Effect of Increasing Spacing

- Increases
... more When the spacing between conductors increases, the corona effect tends to increase as well. This is because the electric field intensity between the conductors decreases with an increase in spacing. As a result, the breakdown voltage of air increases, leading to a higher chance of corona discharge occurring at the higher spacing.

- Explanation: As the spacing between conductors increases, the electric field strength decreases. This decrease in electric field strength at higher spacings can facilitate the breakdown of air and increase the likelihood of corona discharge. Therefore, the corona effect is more likely to occur when the spacing between conductors is increased.

- Impact: The corona effect can result in power loss, audible noise, radio interference, and even damage to the transmission lines. Therefore, it is essential to consider the spacing between conductors to minimize the corona effect and its associated consequences.

In conclusion, the corona effect increases when the spacing between conductors increases due to the decrease in electric field intensity, leading to a higher likelihood of corona discharge. Understanding this relationship is crucial for the efficient and reliable operation of electrical systems.
