Answer:
Use the formula:
P= VI
40= 220×I
I= 40/220=2/11 A = 0.19(approx.)
Now for resistance,use this formula:
V= IR
220=2/11×R
R=220×11/2=110×11=1210 ohm.
Explanation:
Current= 0.19A (approx)
Resistance= 1210 ohm ...

Answer:
I =2/11
R=1210
Explanation:
I=P/V
=40/220
=2/11
R=V/I
=220/(2/11)
=220×11/2
=110×11
=1210
