An electric iron rated 220V has a resistance of 60 Ω. Calculate the current through it when it is connected to a wall socket and switched on.
Thanks..!!
Assuming that Ohm's law holds then
I=V/R
I=220/60
I=3.66A
In practise the resistance will rise with temperature and the current will be less than you expect.
V = I R
220V = I * 60 ohm
I = 220/60
I = 3.2
