Since power is the amount of work done over a period of time (joules/sec), the higher voltage delivers a higher amount of work per second, per coulomb. If we used a lower voltage to output the same power, the Coulombs per second have to increase (higher current/amperage) because the lower voltage has lower joules for each unit coulomb, leading ...

Higher voltage systems also charge differently than lower voltage systems and can provide faster charging; they are more efficient because less current is required for the same amount of power. Furthermore, by increasing the voltage with the same amount of current, more power can be delivered to the cells through DC-DC fast charging.
A higher voltage battery provides more power to the motor, resulting in faster operation speed and greater torque output. With a high-powered motor that runs on more juice, you can work harder without frequent recharging breaks.

Let''s delve into a simple mathematical example: a light bulb operates at 120 volts and has a resistance of 240 ohms.
But physically, whenever a battery is charged, the voltage applied externally must be higher than the battery voltage. Otherwise, you''d do nothing (external potential = battery potential, i.e. no current flows), or discharge it (external potential < battery potential, i.e. the battery provides your external "charger" with power, not the other ...
In simpler terms, higher mAh means a battery can provide power for a longer duration. The capacity of a battery determines how long a device can run before it needs to be recharged.

Generally speaking, it is easier to start an engine in a warm environment than in a cold environment. The rating refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts. The higher the CCA rating, the greater the starting power of the battery. Reserve capacity (RC):
In the context of power tools, higher voltage generally signifies a greater amount of power being delivered to the tool''s motor, leading to enhanced performance. For instance, when comparing two power tools with the same motor design but differing voltages, the tool with the higher voltage will generally deliver more power and performance.

In reality receivers run behind transformers which convert high voltage to low (constant e.g. 230V in Europe). So in the above scenario when we increase the voltage in the power plant, then we just need to change transformers (their resistance) - no need to change receiver''s resistance. All of this is transparent to the end-user.

The battery is initially at zero volts, so no charge is on the capacitor. Slide the battery slider up and down to change the battery voltage, and observe the charges that accumulate on the plates. Display the capacitance, top-plate charge, and stored energy as you vary the battery voltage.
The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).

In typical discussion of AC voltage, we refer to the rms voltage. So when you have a $120 V_{AC}$ line, the peak voltage is in fact $120sqrt 2 approx 170 V$ If you put a capacitor across the line, it will have an instantaneous voltage of $170 V$ at the peak. If you drive a resonant circuit, the peak voltage can be even higher.
