What are the effects of Electricity

The Effects of electricity Electricity is  form of energy which could not be seen,but its presence could be detected due to numerous effects it has in  our daily living. 1. Mechanical effect   An electric fan  for ventilation through the rotation of its blades; A vacuum...

Using multimeter VOM as voltmeter for ACV test

The Ac voltmeter is used to measure alternative current voltage or electrical pressure of a circuit. This instrument is connected across the circuit and it does not require correct application of the polarity . The unit of measure is volt(V). Note;  If the voltage range is unknown get the estimate value by setting the knob at the top level or should be   at 1000 V before measuring...

How to use multimeter as voltmeter DC voltage test

USE Multimeter as voltmeter The DC voltmeter is used to measure direct current voltage or electrical pressure of a circuit. the unit of measure is in volt(V). Multi-meters can be used as voltmeter and this is done by connecting the instrument across the circuit . It requires correct application of the polarity. Your circuit must be powered up in conducting this test Procedure:  Check the...

Using a Multimeter/multi-tester: Preliminary setup and Safety precautions

Multi-tester (VOM-volt/ohmeter) also called multimeter is designed to measure different magnitudes of electrical units:voltage,current and resistance. It incorporates the functions of a voltmeter,ohmmeter,and Milli-ammeter into one device. A multimeter maybe Digital (DVOM/DMM) or Analog. Parts...

Power in parallel Circuits

Power dissipated by each individual resistance is simply added to find the total power dissipated by the series circuit. This same procedure also applies to parallel circuits. If there are five resistive branches in a parallel circuit and each was dissipated 1 watt of power, the total power...

Series and parallel resistance circuit :explanation

The familiarity of the few circuit building blocks is important in  understanding complex circuits. In this post I will explain the most important ideas in  DC circuits. From my previous posts I discussed about the Ohms law . This is a continuation of the post about  simple direct...
