What is the power voltage available at home?

Electrical power is used globally at different amplitude and frequency. Basically electrical power voltage for any country indicates that the line voltage for home appliances. For example-main power voltage in Bangladesh is 220 V at 50 Hz, which means usually residential connected voltage will be 220 V at frequency 50...Read more

SI unit of voltage

Voltage is the difference of energy of two points in any electrical circuit. This is a simple way to know about voltage on electrical point of view if we consider any electrical circuit. Now do we know how to express voltage? Suppose someone ask you: what is your weight? Our...Read more

Phantom power voltage

Phantom voltage This is a kind of voltage appeared in meter to any metal conductors or any metal due to adjacent conductors. It happens due to capacitive coupling between conductors (ungrounded conductors basically). But there is no voltage source or any type of load connected with this. This phantom voltage...Read more

Different types of voltage regulators

Voltage regulator Voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements. Voltage regulator is actually used to maintain constant voltage level. Types of voltage regulatorRead more

Difference between volts and amps

  ** Voltage does not directly kill any person where current does. Actually without the presence of voltage current cannot flow through anything. But main concept is voltage cannot circulate but current that circulation can cause death of human.Read more

DC voltage symbol

Voltage is used for source unit in an electrical circuit. There are two types of voltage source used in electrical circuit theory: DC voltage source and AC voltage source. In practical application and also in various mathematical problems, we need to express voltage in short form. There are some definite...Read more

Different ratings of lead-acid type battery are used in cars. Full chart of various battery voltages with charge state is given below: *This is Open circuit voltage reading...Read more

AA Battery Voltage: Measurements and Applications Guide

An AA battery is composed of a single electrochemical cell that may be either a primary battery (disposable) or a rechargeable battery. The exact terminal voltage and capacity of an AA size battery depends on cell chemistry. An AA battery—also called a double A or Mignon (French for “dainty”) battery—is...Read more

Kirchhoff’s voltage law

Kirchhoff’s Voltage Law (KVL) is very fundamental law in basic electrical engineering. Electrical Circuits are basically of two types- series and parallel. Generally, KVL is used in series circuits whereas Kirchhoff’s Current Law (KCL) is used in parallel circuits. By applying KVL, we can easily solve the unknown voltages without...Read more

Voltage rating in USA

Every country has different rules regarding distribution of electricity for appliances and lighting. International Electrotechnical Commission (IEC) publishes the standard of voltage, frequency and plug types for domestic appliances. According to IEC, following standard of voltage and frequency is maintained in USA. Plug Type Type A and Type B are...Read more
