Running the battery with a constant current load, I observed the output voltage gradually rise over time. The cause was fact that the internal power dissipation produced a temperature rise in the pack, and the output voltage rises (all else being equal) with temperature. Current is simply the rate of change of charges per second. I=dQ/dt.

The wheel is VERY light, yet the motor I am using cannot handle the torque required to run it, resulting in the motor creating a burning smell. This is an 18V motor that I connected to a 12V 2.2 A supply. If I lower the current further, wouldn''t the speed decrease along with the torque? Or is voltage related to speed and torque related to current?

Current does not always split equally – often there will be more current in some branches than in others Since 10 A flows into the junction (the total current from the battery), 10 A must flow out of the junction. The question

It is known that current in a series circuit remains the same. The current is the same at any part of a simple series circuit. But that doesn''t mean the current stays the same if you change the circuit. An LED drops around 1.5 to 3V when it''s working normally.

For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.

Battery voltage will match the charging voltage while on charge as long as charging current can be supplied. Once off charge (disconnected) battery voltage may sag a little to ''rest'' voltage depending on battery type. If you charge a lead acid (car battery) at let''s say 14v, the battery will be at 14v while charging.

The current through the motor will vary continuously and you should be able to see a current ripple on top of whatever slower changes of the current may be due to speeding up or load changes.

As a battery voltage drops under load, there are three things happening: 1) The internal resistance of the battery is increasing. This happens because as a battery discharge, the electrolyte inside the battery starts to break down and this creates additional resistance. 2) The amount of current that can flow through the battery decreases.

This voltage difference drives current through the circuit, from one terminal to another, and back through the battery. As the current flows, the same amount of charge passes through both sides of the battery, ensuring equal current on both sides.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
When a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction.

For example, common battery voltages include 1.5 V and 9 V. circuit A closed loop through which current moves - from a power source, through a series of components, and back into the power source. Originally, current was defined as the flow of charge from positive to negative.
However, current more than likely won't (depending upon the age/use of the battery). The reason why is because the voltage potential difference - the "excess holes on the positive end" and the "excess electrons on the negative end" - is relative to a given battery.
