Can use the formula like p=i^2*r or power=(V^2)/R ??
Anyways the above problem can be solved.

p = i^2r this is right i=v/r a/c ohm's law.
p = 7/10 * 7/10 * 20.
p = 9.8W.
p = 7/10 * 7/10 * 20.
p = 9.8W.

Lets make this easy!
P = v^2/R.
14x14 = 196.
196/20 = 9.8W.
P = v^2/R.
14x14 = 196.
196/20 = 9.8W.

I=V/R.
I=24/20
I=0.7.
W=VI.
W=14*-0.7
W=9.
I=24/20
I=0.7.
W=VI.
W=14*-0.7
W=9.

v=i*r
i=v/r
i=14/20=0.7
W=V*I
W=14*0.7=9.8
i=v/r
i=14/20=0.7
W=V*I
W=14*0.7=9.8
