How many voltages and currents does the battery have
19.5: Alternating voltages and currents
Batteries supply fixed voltages, and circuits with batteries will almost always have DC current. The voltage that is supplied between two of the sockets in a household electrical …
21.2: Electromotive Force
If you connect an excessive number of 12-V lights in parallel to a car battery, they will be dim even when the battery is fresh and even if the wires to the lights have very low resistance. This … 21.2: Electromotive Force - Terminal Voltage - Physics LibreTexts

Why do batteries with the same voltage have different currents?
Experts say "current depends on voltage". So, if the voltage is high, current would be high. Agreed; (I = V/R) If the voltage is low, the current would also be low. Agreed -> I = V/R But why then do two different batteries available with the same voltage (say 2 V) not
20.1: Batteries and Simple Circuits
Modeling real batteries is not so different from modeling ideal batteries, since one only needs to include an internal resistance into the circuit. The key difference with a real …

voltage
There is a charge controller chip inside the phone that determines how much current to put into the battery. Generally lithium ion batteries are charged with a constant current until the cell voltage reaches a specific level, at which point the charge controller switches ...
Voltage Cells in Series
When one voltage cell''s positive terminal is connected to another''s negative, the combined output is the sum of the cell terminal voltages, and the cells are said to be in series. Output Voltage and Current Figure 1(a) shows a battery of four cells connected in series where the negative cell terminal is connected to the positive cell …
What is Battery Voltage?
Voltage is measured in volts (V), with most household batteries ranging from 1.5 volts (like AA batteries) to 12 volts (like car batteries). The voltage of a battery …
What Is the Voltage of AA & AAA Battery?
Types of AA and AAA batteries available and their voltages Zinc carbon AA and AAA battery Zinc carbon batteries have a nominal voltage of 1.5V and a nominal charge of 500-600 mAh for AAA …
20.5: Alternating Current versus Direct Current
Alternating Current Most of the examples dealt with so far, and particularly those utilizing batteries, have constant voltage sources. Once the current is established, it is thus also a constant. Direct current (DC) is the flow of electric charge in only one direction. It is ...
19.2: Electric Current
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 …
Battery Basics: Series & Parallel Connections for Voltage
Effects of Series Connections on Voltage When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts.
What are the highest DC and AC voltages or currents that can be …
[Addendum] Interestingly (I would have said otherwise), paralysis occurs for lower currents at the line frequency (50-60Hz), as shown on the following picture (source, slide 8). It seems the human body has enough capacitance to allow more current at AC - meaning mains voltage is more dangerous than DC of same voltage as proven in …

19.5: Alternating Currents
Unlike direct current (DC), where the currents and voltages are constant, AC currents and voltages vary over time. Recall that most residential and commercial power sources use AC. It is often the case that we wish to know the time averaged current, or voltage.
Back to basics: PV volts, currents, and the NEC
PV arrays can have hundreds of volts on the wiring at dawn and dusk even when the sun does not directly illuminate the fronts of the modules. Hazardous voltages on exposed terminals in dc combiners, disconnects, and the input terminals to inverters will be present.
