The main power supply in India is at

220 {~V}

, whereas that in the US is at

110 {~V}

. Which one among the following statements in this regard is correct?

View answer and explanation

Correct option: A

110 {~V}

is safer but more expensive to maintain

Option A (

110 {~V}

is safer but more expensive to maintain) is correct because lower voltage is generally safer but requires higher current for the same power, leading to increased losses and maintenance costs.
