Basically, "frequency" applies to AC, not to DC. If you want to assign it a frequency, the frequency is zero. The amount of volts is not relevant.
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.
No.
12 volts DC
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
dc - the voltage is a constant 12 volts nominally in a normal car battery.
