What would happen if batteries are connected in parallel?
When two identical batteries are connected in parallel it will double the current capacity and the output voltage remains the same as a single battery. For example, suppose two batteries of same rating i.e. 1800 mAh, 12 V are connected in parallel, the output voltage ...

Difference between capacitors of same value but different sizes
I would like to know why some capacitors have the same value (capacitance) but their sizes are different? What is different between those capacitors? For a given (fixed) set of constraints: Manufacturer, Manufacturing technology, Dielectric type, Target application, i.e.: decoupling, general purpose, high-frequency or power line …
Batteries, current, and Ohm''s law
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.
amperage
But different amount of work needs to be done to achieve that same flow and hence different amount of power in both the circuits (P=VI) A good analogy is a water, so current (rate of flow) is a flow of water where as the voltage is analogous to pressure in the system that will cause the water to flow (ie current).

Battery Voltage: Understanding the Power Behind Your Devices
Batteries are an integral part of our daily lives, powering everything from smartphones to cars. At the heart of a battery''s ability to provide power is its voltage. Understanding battery voltage is not just a matter of technical knowledge; it''s essential for ensuring device compatibility, safety, and optimal performance.
Why are different currents used for charging batteries with the same voltage …
A battery charger must produce a voltage a little higher than the battery voltage - how much higher depends on the battery chemistry, temperature, and other things. 1 Amp and 2 Amp chargers for a given battery type will produce the same final voltage, but the 2 Amp charger can deliver a higher currrent into a discharged battery.

Battery State of Charge: Understanding the Basics
Different battery chemistries have different discharge signatures, which can affect the accuracy of voltage-based SoC methods. To get accurate readings, the battery needs to rest in the open circuit state for at least four hours, although battery manufacturers recommend 24 hours for lead acid batteries.
