AC Voltage
Posted: Thu Nov 03, 2011 5:25 pm
I know that AC voltage directly from the plug is rated at 230V, 50Hz. But what is the Amp rating?
Besides, an AC plug has 3 pins (live, neutral, earth). What are their use? Is the earth pin connected to the metal casing of the circuit/product to prevent shock etc. ? The live wire carries AC voltage which is a sine wave ? The neutral to lead beck excess voltage back to the source (So is live like +, neutral is like - but just in AC ?)?
