Answer 1

$\huge\underline{\underline{\bf \green{Question-}}}$

If an electric heater of 220 volt draws the current of 5 ampere, then in 5 hrs how many units will be consumed?

$\huge\underline{\underline{\bf \green{Solution-}}}$

$\large\underline{\underline{\sf Given:}}$

• Voltage ( V ) = 220 volt
• Current ( I ) = 5 A
• Time ( t ) = 5 hrs

$\large\underline{\underline{\sf To\:Find:}}$

• How many units will be consumed

✪$\large{\boxed{\bf \blue{Power= VI }}}$

$\implies{\sf 220×5}$

$\implies{\bf \orange{Power (P) = 1100\:Watt} }$

✪$\large{\boxed{\bf \blue{Electric\:Power(E)=Pt}}}$

$\implies{\sf 1100×5 }$

$\implies{\sf 5500\:Waat.h }$

$\implies{\bf \red{E = 5.5\:kWh\:\:\:or\:\:\:5.5\:units }}$

$\huge\underline{\underline{\bf \green{Answer-}}}$

Option ( c ) 5.5 units

${\bf \red{5.5\:units}}$ will be consumed

Answer 2

Answer:

5.5units will be consumed
