Question

An electric iron has rating of 750w ,220 volts calculate the current andvresistance when in use

Answer 1

Hi friend
--------------
Your answer
--------------------

Power of an electric iron = 750 W

P = 750 W , V = 220 V

Current (I) = ?

We know,

P = V × I

=> 750 = 220 × I

=> I = 750/220

=> I = 3.40 A (Approximately)

Now,
---------

Resistance (R) = ?

We know,

V = I × R

=> 220 = 3.40 × R

=> R = 220/3.40

=> R = 64.70 Ω (Approximately)
