    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?

  • 110 V is safer but more expensive to maintain
  • 110 V is safer and cheaper to maintain
  • 110 V lead to lower power loss
  • 110 V works better at higher latitudes
  • Explanation:

    The higher the voltage, the lesser the current. The lesser the current the lesser the loss of power in transmission. Thus with 110 v the loss of power makes it more expensive. On the other hand, higher voltage is more dangerous if accidentally touched or if there is an accidental short circuit.
