Volts alone is not dangerous, but volts does causes amps. Amps can be dangerous to you if it flows through your body. That's because your brain, your nerves, and your muscles ... including your heart ... all operate on tiny natural volts and amps. They can all go haywire when big ones get in from outside your body.
How much current? Volts/Amps = Ohms. In your case Volts = 1.5
Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.
You give it more volts and it will burn out something!!
No
it will be no DC not unless diodes and capacitors are applied. rephrase the question
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
AC - use a step-down transformer. DC - simplest but most wasteful, use a dropping resistor (in series). Otherwise it is costly.
dc - the voltage is a constant 12 volts nominally in a normal car battery.
12 volts DC.
13.5-16 volts DC
12 volts DC
The danger is in the voltage, not if it is ac or dc. For instance, 12v dc or 12v ac makes no difference in body contact. Neither will shock you. Usually 24 volts will not shock either. When you get to 48 volts or greater, then you have a chance of shock. 100 volts Ac or Dc shocks basically the same. 120 volts AC is actually 144 volts peak to peak, so 120 volts AC is slightly worse than 120 volts DC. Amperage is actually what kills. A "Taser" voltage can be as high as 50,000 V but the amps are so slow that it doesn't do permanent damage. Commonly people are shocked accidentally by a spark plug wire on a car or a lawnmower with no lasting or ill effects. This voltage can range from 15,000 volts to more than 50,000. These systems have very low amperage.
30VAC is not equal and will never be equal to 30VDC. If you rectify 30v ac to DC you will get a voltage lower than 30v because there would be a voltage drop across the rectifier=diode,capacitor,resistor and transistors or thyristor, depending on the make of the rectifier.AnswerAs the questioner makes no mention using a rectifier, yes, 30 V a.c. is exactly equivalent to 30 V d.c. This is because a.c. voltages are root-mean-square values (unless otherwise stated) which, by definition, correspond to d.c. voltages.
DC
I Can Not answer. It is my question.
