P=VI

I=P/I

I = 2 000/100

I= 20 Amps

P=IE thus I = P/E

I = 2,000w/100v = 20a ←

But I question where you would ever find 100vac mains?? Did you mean 120vac as is standard in the US? then I = 2000/120 = 16.7a

Assuming the supply mains are single phase, and the iron is purely resistive, then this can be answered by simple Watt's Law.

P=VI

I=P/I

I = 2 000/100

I= 20 Amps

P = EI

2000 watts = 100 v x I

I = 20 amps

that assumes the device is designed to draw 2 kW at 100 volts.

2,000/100 = 20 amps. P divided by E equals I. P divided by I equals E. P is the measure of power when you multiply E x I. E is electromotive force. I is current flow.
