There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.
Thereof, what color is the positive wire?
Wiring Color Codes. Black wires identify negative or hot wires. Switches connect on negative side of battery to the load (light). White wire is used to identify the positive polarity.
Which color wires are positive and negative?

|Positive (of a positive grounded) circuit||N||white|
|Negative (of a positive grounded) circuit||L-||black|

What color is positive in electric wire?
Chapter 2 - Color Codes
|Protective ground||PG||bare, green, or green-yellow|
|2-wire ungrounded DC Power System|
|Positive||L+||no recommendation (red)|
|Negative||L-||no recommendation (black)|
The wiring in some homes is encased in conduit. The metal conduit is allowed to serve as the ground conductor, so bare or green wires are not used. The white wire is the neutral, and all other colors are hot. Electricians often use black, red or blue wires to deliver electricity to a circuit from the main panel.
So conventional current flows from positive terminal to negative terminal and, electron flow is the reverse. A higher flow of electrons occurs when the positive terminal becomes more positive (compare a 1.5 volt battery with a 9 volt battery - for a given load resistance, more current flows.
Step 3: With both cars off and in Park, connect the jumper cables in the following order: (1) Connect one red clamp to the positive (+) battery post of the "dead" battery. (2) Connect the other red clamp to the positive (+) post of the good battery.
These terminals are also almost always color-coded for easy identification: The positive terminal (+) is typically red, while the negative terminal (-) is typically black. Note that some speakers are bi-wire capable, which means the red and black terminals come in pairs for a total of four connections.
Since red is the color of blood, it has historically been associated with sacrifice, danger and courage. Modern surveys in Europe and the United States show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love and joy.
Any circuit's black wire should be considered hot or live. Black wire is never used for a ground or neutral wire and should be used as the power feed for a switch or an outlet. A black wire is often used in a circuit as a switch leg, the connection that runs from the switch to the electrical load.
Spray both terminal ends with anti-corrosion solution. Attach and tighten the positive battery cable (Red). Attach and tighten the negative battery cable (Black). Ensure that all cable connections/ hold downs are properly tightened.

When installing a mower battery, always connect the positive cable first. The positive cable is red. It attaches to the battery terminal post marked with a plus sign, the letter P or the word POS. Attach the negative cable last.
Electrons are negatively charged, so they will be attracted to the positive end of a battery and repelled by the negative end. When the battery is hooked up to a device that lets the electrons flow through it, they flow from negative (anode) to positive (cathode) terminal.
In DC circuits, the positive pole is usually marked red (or "+") and the negative pole is usually marked black (or "−"), but other color schemes are sometimes used in automotive and telecommunications systems.
It depends on the situation you refer to.The ground in a DC battery circuit is the negative point(-).The - of the battery is the most negative because there will be located more electrons, who,as you said,flow towards the positive terminal in order to equalize the number of electrons of both points.
Attach the red, positive cable clamp on the other side of the jumper cables to the functioning vehicle's positive (+) battery terminal. Connect the black, negative cable clamp to the working battery's negative (-) battery terminal. Walk over to the car with the dead battery.
The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the "wall wart" power supplies. Usually* the wire with the white stripe or the dashed lines carries the "positive" (+) end, while the other, unmarked wire carries the "negative" (-) end.
By convention, this typically is where you hook the negative terminal of a battery, but that is not always the case. Strictly speaking, the negative terminal is not ground, it may be connected to ground, and so be at ground potential. In a car, negative terminal of battery is connected to chassis.
The terminal of a battery or other voltage source that has more electrons than normal; electrons flow from the negative terminal through the external circuit to the positive terminal.
The jumper cables are marked with colors or stripes to help you keep track of the two separate wires. Attach one end of the positive cable clamp to the positive terminal of the dead battery (the positive cable may have a stripe, or if the cables are marked with red and black, the red cable is positive).
In some high-end speaker wires, the insulation is clear, or see-through, enough to see the bare wires. When this is the case, usually the silver wire will be the positive polarity and the copper wire will be negative.
During jump-starting, we connect the boosting battery to ground rather than to the dead battery's - terminal for the simple reason that this provides a more direct return path to the good battery which is powering the dead car: the return current does not have to travel through the dead battery's minus terminal hookup
A car battery usually holds 48 amps so if you take that it charges at approximately 1 amp per hour you can work out how long it will take to charge your battery with various amperage chargers. Charging your battery with a four amp charger will take about 12 hours to get a full charge out of this low amperage.
