Given :-

  • Power = 400 Watt
  • Voltage = 220 Volt

To Find :-

  • Current = ?

Solution :-

As per the provided information in the given question, we have been given that the Power of the Device is 400 Watt . Voltage is given 220 Volt . And, we have been asked to calculate the Current of the Device .

For calculating the Current , we will use the Formula :-

  • Current = Power / Voltage

Therefore , by Substituting the given values in the above Formula :-

⇒ Current = Power / Voltage

⇒ Current = 400 / 220

⇒ Current = 1.81

Hence :-

  • Current = 1.81 Ampere .
