Due to capacitance OR INDUCTANCE we get reactive power (Q).
The real power (S) depends on only resistance.
S=VI=(I^2)/R.

As we know that:
P = VI.
& V = IR according to Ohm's law.
So P = (I^2)R.
P = VI.
& V = IR according to Ohm's law.
So P = (I^2)R.

P = I^2*R.
P = 6.50mA^2*2000.
P = 0.0845.
P = 84.5 mW.
P = 6.50mA^2*2000.
P = 0.0845.
P = 84.5 mW.
