Question

A toaster operating at 240V has a resistance of 120Ω. The power is
(a) 400 W
(b) 2 W
(c) 480 W
(d) 240 W

Answer 1

the answer is given in the picture.

Answer 2

hey @User here's ur answer ,

The correct option is ( c )

How.....????

here's have a look......

Given,

potential diff = pd = 240V

Resistance = R = 120 ohm .

Now we have to find Power ( P )

before finding power,
Current ( I) should be fine first ....

I = V / R

I = 240 V / 120 ohm

hence Current = I = 2 ampere.

Now ,

we know that ,

p = V × I

put the value....

240 × 2

= 480 W.

Hope it might be helpful !!
