I read that current enters an appliance through live wire and leaves through the neutral wire.Consider the appliance to be a light bulb.Now my question:
1.Shouldn't the current first travel to the appliance though the live wire,become zero,and then flow from neutral to live? Because AC reverses direction?
2.The current is alternating in magnitude.But why is the bulb glowing with the same power? Should not the bulb first glow very brightly,then dim and finally gets off and then again starts glowing??
