The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. Key …
Very loosely speaking; Potential Difference drives current. If you connect a 9V battery to a circuit without any components. The 9V battery means that each Coulomb of charge has 9 Joules of energy acquired from the battery; and this energy must be dissipated in the circuit wires, since there is no resistor, thermistor, or LED etc. for each ...
When the battery current drops to 0.1 amp, or if 6 to hours have elapsed at the absorption voltage, the charger automatically switches its output from 14.4 V to 13.2 V. So it may take the better part of 20 hours to reach the float stage. Add another 24 hours to that and you are at 44 hours. Throw in another 4 hours for good measure and you get ...
Technically, current may or may not flow when a wire is connected that way. It all depends on whether or not there is a potential difference in charges between those two terminals. If the difference is small, little/no current will flow. This holds true for any wire …
Unless you have a circuit, current does not flow. There will be some minor current which goes through the air to complete the circuit, but that will be very minor indeed compared to self discharge. You won''t notice the effect. Connecting both sides of the battery can discharge the battery faster. The ground, like all materials, has a resistivity.

Scientific Explanation: Over-Discharge: When a battery is excessively discharged, the voltage can drop to a point where the chemical composition inside the battery changes. This change can lead to the weaker cells in a battery pack reversing their polarity. Cell Imbalance: In a battery pack composed of multiple cells, if one cell discharges more quickly …
The potential across the battery during discharge. Note that there is a slope in the potential in the metal strips (blue and red lines) due to Ohmic drop. Note that in metals, the current is conducted by electrons, but by definition, in the opposite direction to the electric current. In other materials, charge carriers can be negative or positive.
This force is responsible for the flow of charge through the circuit, known as the electric current. A battery stores electrical potential from the chemical reaction. When it is connected to a circuit, …
It could be that the alternator isn''t performing its functions which include charging the battery or, worse yet, it could be draining the battery. A thorough diagnosis can identify if the alternator is at fault for your battery drain, or you can install a good new or remanufactured alternator to see if it clears up the issue.
The current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m. The resistivity can be found from the table on page 535 in the textbook. The area is the cross-sectional area of the wire.

When the capacitor is first charged, it has received $frac{1}{2}C(+V)^2$ joules of energy from the battery.. By reversing the battery, you create a potential difference which causes current to flow in the opposite direction, which will at first discharge the capacitor, until the voltage across it returns to zero. At that point the capacitor stores no energy at all.
