Question

an electric iron has a rating of 750 watt, 220 volt calculate the current passing through it​

Answer 1

Given:-

• Power of electric iron ,P = 750 W

• Potential Difference ,V = 220v

To Find:-

• Current Passing through it ,I

Solution:-

As we know that the relationship between Power , Potential Difference and Current .

• P = VI

Where,

P is the power of iron

V is the Voltage or Potential Difference

I is the electric current

Substitute the value we get

➺ 750 = 220 × I

➺ I = 750/220

➺ I = 3.40 A

Therefore, the electric current passing through is 3.40 Ampere.

Extra Information !!

• The flow of charge is called current.

• The charge passing per unit time through a given place is the magnitude of electric current at that place.

• SI unit of current is Ampere (A).

• If one coulomb of charge passing through a place in one second, then the current is said to be one ampere.

Mathematical term

•I = Q/t

here,

I is the current

Q is the charge

t is the time.

Answer 2

$\large{\bigstar\underline{\textbf{Given:-}}}$

❆Power = 750W

❆Potential Difference = 220V

$\large{\bigstar\underline{\textbf{Find:-}}}$

✬Current passing through it.

$\large{\bigstar\underline{\textbf{Solution:-}}}$

we, know

$\huge{\underline{\boxed{\sf I = \dfrac{P}{V}}}}$

$\orange{\sf where} \footnotesize{\begin{cases} \pink{\sf Power, P = 750W} \\ \purple{\sf Potential \: Difference, V = 220V} \end{cases}}$

☯$\textsf{\underline{Substituting\:these\:values\:in\:the\:formula:-}}$

$\dashrightarrow\sf I = \dfrac{P}{V}$

$\dashrightarrow\sf I = \dfrac{750}{220}$

$\dashrightarrow\sf I = \dfrac{75 }{22}$

$\dashrightarrow\sf I = 3.409A(approx.)$

$\dashrightarrow\sf I = 3.4A$

$\therefore \underline{\purple{\footnotesize{\sf Current\: passing\: through\: electric\:iron = 3.4A}}}$
