Answer 1

Here You Go,

Hope It Helps!

Edit : I took voltage to be 240 V ( Sorry for Silly Mistake). Just put the required value and You will get your answer.


Then You will get-

R= 625 Ohms

P= 100 W

Answer 2

hey mate ;

1. Power = V×I= 250×0.4= 100W

2.resistance = V/I= 250/0.4= 625 ohm.

hope it helps :)
