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

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:-

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

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

Answer 2

Answer:

The power is 1760 watt

Explanation

Given :- I = 8A

V = 220 v

To find :- P = ?

Solution :-

We know that P= VI

So, p = 220 × 8

p = 1760

Hence the power is 1760
