calculating the current requirement

[su1c1d4l]

mga gurus, pano pano po ba mg calculate ng current requirement in AC if you have 100watts of lighting, 220VAC? 

[alyas]

P=IV  Power =  Current x Voltage

[su1c1d4l]

P=IV  Power =  Current x Voltage

thankz,this is the power formula for instantaneous power,right? is this the one im going to use or the average power formula?

[alyas]

its applicable to both

thanks po.

I = P / V,
I- current
p-power (watts)
v-volatge.

I = VA / V,
VA-voltampere (apparent power)
