Question

The current flowing through a heating element is 8.0 A when connected to a 220 V
supply. Calculate the power rating of this element.

Answer 1

Answer:

Given,

Current (I) = 8A

Voltage (V) = 220V

Power (P) = ??

We know that,

P=VI

=> P= 8×220

=> P= 1760W

So, therefore power = 1760 W

Answer 2

Given:-

$\sf current = 8A \\\sf \: voltage = 220v$

To find:-

• $\sf Power$

Formula:-

$\underline{\underline\pink{\boxed{\bf power =voltage \times current }}}$

Solution:-

$\implies\sf power \: = 220 \times 8 \\ \implies\sf \: power \: = 1760 \: watts$

hence, our required answer is:-

$\underline{\underline\blue{\boxed{\bf \: 1760 \: watts }}}$

More to know:-

other formulas of power:-

$\underline{\underline\green{\boxed{\bf power = {current(i)}^{2} \times resistance(r) }}}$

$\underline{\underline\orange{\boxed{\bf power = \dfrac{ {voltage(v)}^{2} }{resistance(r)} }}}$
