Question

The rms value of alternator is 200V and rms current delivered towards is 3A and phase angle between them is π/6. Find the power delivered.

Answer 1

Heya 

we know that 
Power = E₀ × I₀ cosФ/2    { where Ф is called phase difference between voltage and current .
and  we know that E₀/√2 and I₀/√2 = Er.m.s and I r.m.s  { where E  and I are peak values of voltage and current respectively . 

so we can  write it as 
P = Er.m.s × I r.m.s cosФ
so now just plug the given values 
you will get 
P = 200 × 3 × cosπ/6
=> 600 × √3/2
=>  300√3 Watt
so power = 300√3 Watt.
