In this post i will share with you some useful information about ac vs dc and why it matters to know about it.
Car battery dcv or acv.
Alternating current voltage acv.
The common circuit flow for all battery operated vehicles are as follows.
Cars use direct current and it s based on a 12 volt system.

Dc is direct current and is the kind that comes from batteries usually.

Alternating current or ac is the type used in houses.

This setting is used to measure direct current dc voltage in things like batteries.
1 convert the 230v ac into 9v which the external charger does 2 send this 9v to the controller pcb 3 from the controller pcb wires will go for battery motor any headlights depends upon the model 6v 4 5ah battery has been connected to the pcb.
Sometimes it will be denoted with a v instead.
Ever wondered is a car battery ac or dc.
It s usually a higher voltage like 120v.
In fact a car battery or any other battery releases dc voltage.
For example a dc battery can produce alternating current if it is paired up with an ac converter.
Dcv stands for direct current voltage and acv stands for alternating current voltage.
Turn the multimeter knob to the next highest option 200 acv.
Dc voltage is usually marked as a v followed by a short line with a dotted line beneath it.
The meter should be set at the top end of the voltage you are reading.
The wavy line after a v is ac alternating current voltage and is for checking the mains voltage in your house.
This setting is used to measure the voltage from alternating current sources which is pretty much anything that plugs into an outlet as well as the power coming from the outlet itself.
Choose the range setting.
If you just want to check weather or not you have voltage at any given point place it on 10 volts and the needle should max out.
Knowing the car battery voltage is important if you want to know how to take care of it better.
To measure direct current a battery for example use dcv or v.
Sometimes it will be denoted with a v instead.
If you re testing a 12 volt car battery select the next highest option 20 dcv.
Direct current voltage dcv.
It requires some additional circuits if you want to make it ac.
Select the dc volts position on your multimeter or the 12v setting if you have a dedicated car battery test range.

The dial may have options from 10 to 1000 on the acv side and 5 to 1000 on the dcv side.
