What is the standard electric power transmission and distribution Current in the Philippines?
The current (measured in amperes) depends upon the power drawn over the power lines. Let's say the power station generates 100Mw of power and - ignoring substations and transformers - the voltage is 220VAC. You turn on your TV set, and it draws 100 watts of power.
V=AW
220 = A * 100
2.2 = A
So, your TV set draws a current of 2.2A. When other appliances throughout the city are turned on and off, the current goes up and down.
