12v AC is equal to 12v DC?

No, 12V AC (alternating current) is not equal to 12V DC (direct current). The key difference between AC and DC is the direction in which the electric current flows. In an AC system, the current changes direction periodically, typically in a sine wave pattern. This is the type of electricity that comes from the outlets in your home.

On the other hand, in a DC system, the current flows in one direction continuously. This is the type of electricity that you might get from batteries or solar panels.

While both 12V AC and 12V DC systems have the same voltage level of 12 volts, they are fundamentally different in terms of how the voltage is delivered and the characteristics of the current flow. It's important to use the appropriate type of current for the specific devices or equipment you are working with to ensure proper operation and safety.
