Batteries Theory
A battery converts chemical energy to electrical energy. This conversion enables electrical power to be stored. The purpose of a battery is to store chemical energy and to convert this…
How to Measure Specific Gravity of Battery
Specific gravity is defined as the ratio comparing the weight of any liquid to the weight of an equal volume of water. The specific gravity of pure water is 1.000.…
Battery Terminology
Batteries are used for a wide variety of services throughout technology today. To begin to study battery operation and characteristics, a few terms that are used with batteries must be…
Capacitive Time Constant
When a capacitor is connected to a DC voltage source, it charges very rapidly. If no resistance was present in the charging circuit, the capacitor would become charged almost instantaneously.…
Series Tanks Level Control using PLC Ladder Programming
We need to control level of tanks which are connected in series. Implement program for Series Tanks Level Control using PLC Ladder Programming.
Parallel Tanks Level Control using PLC Ladder Diagram Tutorial
This is a PLC Program to control the level of parallel tanks. Learn the PLC programming using this example.
Series and Parallel Capacitors
Capacitors in series are combined like resistors in parallel. Figure 13 : Capacitors Connected in Series The total capacitance, CT, of capacitors connected in series (Figure 13), is shown in…
Types of Capacitors
All commercial capacitors are named according to their dielectrics. The most common are air, mica, paper, and ceramic capacitors, plus the electrolytic type. These types of capacitors are compared in…
Capacitance
Capacitance is the ability to store an electrical charge. Capacitance is equal to the amount of charge that can be stored divided by the applied voltage, as shown in below…
Capacitor
Electrical devices that are constructed of two metal plates separated by an insulating material, called a dielectric, are known as capacitors (Figure 10a). Schematic symbols shown in Figures 10b and…
