8.4: Energy Stored in a Capacitor

Most of us have seen dramatizations of medical personnel using a defibrillator to pass an electrical current through a patient''s heart to get it to beat normally. Often realistic in detail, the person applying the shock directs another person to "make it 400 joules this time." The energy delivered by the defibrillator is stored in a capacitor and can be adjusted to fit the situation. SI

How to calculate battery energy?

How do you calculate battery storage capacity?

The formula for calculating battery storage capacity is given below: Battery Capacity = Current (in Amperes) × Time (in hours) Battery Capacity represents the total amount of electrical energy a battery can store, typically measured in ampere-hours (Ah) or watt-hours (Wh).

How to get voltage of a battery in a series?

To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .

What is the unit of measurement for battery energy?

The unit of measurement for battery energy can be: joule [J] or Watt-hour [Wh] or kilowatt-hour [kWh]. Calculate the energy content of a Ni-MH battery cell, which has the cell voltage of 1.2 V and current capacity of 2200 mAh. Step 1. Convert the battery cell current capacity from [mAh] to [Ah] by dividing the [mAh] to 1000: Step 2.

What determines the nominal voltage of a battery?

Thus the nominal voltage is determined by the cell chemistry at any given point of time. The actual voltage produce will always be lower than the theoretical voltage due to polarisation and the resistance losses (IR drop) of the battery and is dependent upon the load current and the internal impedance of the cell.
