How do you ground in dc circuits. I've seen many circuits around the net with plus ve terminal from the battery and no -ve terminal to the battery and ground symbols.. wat to do in these circumstances?

The physical body of your DC Equipment is always your GROUND. This GROUND is where you also connect your -VE.

How do you ground in dc circuits I have seen many circuits around the net with plus ve terminal from the battery and no ve terminal to the battery and ground symbols what to do in these circumstances?
In many cases, a ground symbol is used to save drawing extra lines in a diagram and/or to show that a metal cabinet is used as a return path to save wiring in the ground side.
How do you replace the battery in a 2004 mini cooper S?
The battery should be in the hatch compartment (behind the rear seats), under the floor mat. Disconnect the negative terminal (black), then the positive terminal (red). Remove the battery, and install the new one in the same position. Reconnect the positive terminal, then the negative terminal. NOTE: The terminals are also designated by plus or minus symbols.
2002 Honda CRV radio6disc player just stopped working and is displaying weird symbols what's going on?
Remove the battery terminal and fix it again. I hope it will work
What is the difference between hydraulic and pneumatic symbols?
It all comes under Fluid dynamics/mechanics, and it's the same set of symbols for circuits. Many hydraulic symbols will include a drain to the tank. Pneumatic circuits use the atmosphere as their "tank".
Why are circuit symbols used when drawing electric circuits?
It is often necessary to wire crossing
How do you destroy the circuits on club penguin?
you have to match the symbols the appear on the circles with its matching one
What are definitions of symbols on the battery?
+ = positive - = negative
How do the symbols of additive transformers differ from subtractive polarity?
Using North American standards, when terminal X1 is diagonally opposite terminal H1, the transformer is additive.
How can you determine positive and negative to hook up car battery?
Answer 1 - Automotive Battery Terminal Polarity DeterminationDepending on the brand and model of battery, there could be one or more ways to determine polarity of the terminals. Some batteries may have only one identifier method, while another battery may have a different identification method, and some batteries may 2 or more symbols embossed into/onto the battery top next to each of the terminals. Here are the battery terminal identifiers I have seen over many years:A plus symbol [+] embossed into the battery top next to the positive terminal,A negative symbol [-] embossed into the battery top next to the negative terminal,An abbreviation [POS] for the word positive embossed into the battery top next to the positive terminal,An abbreviation [NEG] for the word negative embossed into the battery top next to the negative terminal.And on some batteries, although they MAY look the same, the diameter of the positive and negative terminals will be different, with the positive terminal being just barely / slightly larger in diameter than the negative terminal.A DC voltmeter can be used to determine terminal polarity.Answer 2 - Battery Cable Polarity DeterminationOn some cars a red cable denotes positive or the terminal has + or pos stamped into it. If you are presented with two cables of the same colour, the one connected directly to the car body is usually the negative cable, and the cable that goes to the fuses is the positive. BEWARE vehicles manufactured before 1970 may have reversed polarity, with the positive cable going to the body and the negative going to the fuses.
Are Ovals used as terminal symbols marking the starting and end of the pseudocode?
No that would be a flowchart.
How do you replace Nissan Micra 1994 battery without knowing the positive and negatives?
Answer 1all batteries have a positive and negative labeled on them. One battery cable should be red and one black the red is positive! Answer 2 The rest of the storyAnswer 1 is correct, but IF you had to ask the question, then answer 1 is incomplete. The labeling on the battery to which answer 1 relates does not say "positive and negative." Instead, symbols are used, and they are embossed in raised symbols on the battery case, next to the terminals they identify. Since they are embossed in the battery case, they usually are NOT a different color, but are the same color as material of the battery case, and you have to really look for them.The positive battery terminal will be identified with a plus [+] symbol next to it, and the negative terminal will be identified with a minus [-] symbol next to it.Also, I think, the two terminals are very slightly different in size [diameter]. Genrerally, the positive terminal will be slightly larger than the negative. I think this was done to help prevent people from connecting the cables backward.Although you can put the slightly larger positive cable connector on the negative terminal on the negative terminal, the negative cable connector will not fit over the negative terminal on the battery. However, this does you no good, once you've incorrectly [reversed] touched the cables to a "hot" battery, which probably will instantly "fry" some of the delicate electronics of your vehicle.As mentioned in answer 1, the polarity of most battery cables are generally indicated by the color of the insulation jacket. Normal protocol 12 volt vehicle electrical systems is that a positive cable or wire will have a red color, and the negative will have a black colored insulation jacket. That is of course, unless someone who did not know what they were doing, replaced one or both of the cables with the wrong color!You can determine if the cable colors are correct by visually tracing them from their terminal connectors to where they go in the engine compartment. If correct, the black negative battery cable will go to a ring connector under a bolt head on the metal engine block. If correct, the red positive battery cable will go to either a solenoid relay mounted on [usually] on the inner fender near the battery, the firewall, or on the starter itself.Once you are certain that you know which battery terminal are positive and negative, AND which battery cables are positive and negative, then replacing the battery is simply a matter of loosening the terminal clamp bolts, removing the NEGATIVE clamp/cable from the battery first, then the postivive clamp/cable.Then remove the old battery, clean all accumulation of dust, dirt, from the battery tray and terminals, and install the new battery. Then clean the cable clamp connectors with a "terminal brush," and install the cables.Intall the POSITIVE cable FIRST, and the NEGATIVE cable last. If there is a safety cover on the positive terminal, replace it over the positive cable clamp.
Why do scientists use in diagrams of electrical circuits?
Scientists use symbols for diagrams of electrical circuits for a simple reason; to save space. The actuall names of the components would take up immense space on the diagram.
