Do electrical equipment work with AC or does the voltage get converted to DC before working anything!! for exampe, if i connect something such as a light bulb directly to an AC outlet, would it work or would it get blown out, why do somethings get blown when using AC
DC is direct current and AC is alternating current. From the names, DC is constant voltage that gives us potential energy directly such as batteries and AC is alternating between positive and negative voltages and has a specific frequency usually 50~60 Hertz. The reason why most devices blow up when connected directly to AC voltage is due to the fact that AC has a higher voltage rating than DC, and most electronic devices operate at lower voltage and therefore you see most electronic devices with transformers in order to convert the high AC voltage to DC voltage. The case of the light bulb is that it can operate by AC voltage, since light bulbs needs the frequency of the AC voltage source in order to keep flickering, however our eyes do not keep up with the flickering speed and see it as constant light.
AC mean alternating current where the positive and negative switch continuously. DC means direct current which there is just one positive and one negative. If you connect a lightbulb to DC or AC it would work since the flow of electricity will work in either direction to power the light. however it all depends what you're using in terms of voltage, watts, etc. if you take an automotive bulb and plugged it into a house out let it would blow. Different components work only for direct current and some only work with alternating current.
