1. Voltage: Battery voltage is measured in volts (V) and represents the potential difference between the positive and negative terminals of the battery. It indicates the force or "push" that drives electrical current through a circuit.
2. Electrical Energy: Electrical energy is the capacity to do electrical work or power electrical devices. It is measured in joules (J) or kilowatt-hours (kWh) for larger amounts.
3. Relationship: The voltage of a battery determines how much electrical energy it can deliver per unit charge. A higher voltage battery has a greater potential to provide more electrical energy compared to a lower voltage battery.
4. Formula: The electrical energy (E) stored in a battery is calculated by multiplying the battery's voltage (V) by its capacity (Ah), which represents the amount of charge it can hold:
E = V x Ah
5. Voltage and Current: Voltage and current (measured in amperes, A) are two fundamental electrical parameters. Voltage represents the electrical pressure, while current represents the flow of electric charge. Together, voltage and current determine the amount of electrical power (measured in watts, W) that can be delivered:
Power (W) = Voltage (V) x Current (A)
6. Battery Capacity: The capacity of a battery, measured in amp-hours (Ah), indicates how much electrical charge it can store. A battery with a higher capacity can deliver more electrical energy before needing to be recharged.
In summary, a higher battery voltage means that the battery has a greater potential to deliver more electrical energy per unit charge. The voltage, along with the battery's capacity, determines the total amount of electrical energy it can store and provide to power various devices and appliances.
