DC output generated by a rectifier circuit, not a wave of pure DC, but the waveform up and down or pulsing. These waves can not be used to distribute electronic circuits.Process of flattening the pulsing waves of rectifier circuit, it can be done by connecting in parallel a large value of filter capacitor to output DC, as in the circuit belowThe capacitor used is usually electrolytic capacitors (

To prevent damage to the LEDs due to the high voltage source, we must put in series a current limiter resistor. Resistance value appropriate to the LED current limiting resistor, can be calculated as follows.The voltage source provided is VS (Volt). We want the LED current is I (Amperes). Assume that the LED forward voltage drop or VD to be produced is 2 V. Note the picture belowThe voltage drop

3-phase electrical voltage that usually denoted by R - S - T wire, when measured with a volt meter, inter-phase (RS, or RT, or ST) will show the number 380 V. But when each phase is connected with the neutral wire (RN, or SN, or TN), will show number 220 V. How could that happen?On the power grid 380 V 3 phase, that distinguishes the phase R - S - T is phase angle, which is odds of 120 °. When we

In electrical circuits, we recognize two types of standard connection, namely: the series connection and parallel connection. When the encounter is the form of connection other than that, basically a variation of the series and parallel connections. Previous articles have discussed the series and will now discuss the parallel connections.Parallel connectionIf several sources, load, or electrical

The amount of electrical energy used in a home is measured by using an electric meter (kWh meter in general term in Indonesia), which is connected to PLN's power supply lines. Calculate the electric meter electric energy usage in kWh units. Electricity bills charged to the user based on the amount of electrical energy consumption. The costs listed in the bill is calculated by using the formula:

A number of electric power can generate power or energy. With electricity we can get a light, sound, heat, movement, and others. The amount of energy produced by an electrical device depends on: - Rating power devices - Long working time device The greater the power the device, the more the amount of energy produced in a certain period. The longer the device worked, the more the amount of energy

In incandescent lamps, electric power converted into the form of light and heat energy. If a light on in an hour, so long as the lamp uses a certain amount of energy. When the lights were on for two hours, the lamp uses energy twice as much from the one hour. From the description above, can be concluded: The amount of energy used is proportional to the time the lights burning. Scale electric

Electrical resistance (R) is the friction or obstacles that are given a substance to an electrical current. With this friction or obstacles, causing the motion of electrons decreases. Barriers that hinder electron movement is called the resistance, while the instrument is called a resistor or resistance. Unit to measure electrical resistance is called Ohm or by the symbol Ω (read Omega).The

Electric voltage (V) is the force that moves electric current to flow along an electrical circuit. According to the theory of electron, a positively charged object if the object lack negatively charged electrons and if it is the excess electron. In different circumstances this is the emergence of the energy charge potential which lies between these objects. Therefore, if a piece of conducting

According to the theory of electron: electrons flow from the excess electrons to the electron-deficient or from the negative charge toward the positive charge. But according to the direction of the current agreement (not the direction of flow of electrons) always moves from the positive to the negative. Look at the pictures belowFigure Flow Theory Based Electricity Electrons: electrons flow from

The flow of electrons moving in an electrical conductor with a certain velocity called the electric current (I). The emergence of electric current because there is a potential difference at two ends of a conductor. While the potential difference in the two conductor due to one end of the conductor to get a force that drives the electrons to move.Electric current will only occur in a closed

Atom consists of nucleus and electrons orbiting the nucleus. The core itself consists of positively charged protons and uncharged neutrons. The electrons surrounding the nucleus are negatively charged. Large load equal protons and electrons, ie e = 1.6 x 10-19 coulombs. Semiconductor materials most widely used in the manufacture of electronic devices is the silicon (Si). The atom consists of

Basically, electrons are in each object, whether solid, liquid or gas. Here are outlined the position of electrons in the composition of an object. Object is something that can be touched or seen with the naked eye.Molecular is the smallest of things can still be divided again and still contains the chemical elements of the object.Atom derived from the word which means not atomos indivisible,

Electronics is the study of the properties and use of the principle of work is the flow of electrons in a vacuum or gas (as in radio tubes) and the flow of electrons in a semi-conductor (such as in transistors). Electronics include radio, radar, television, the industry regulatory system, computer, voice recording, measuring instruments, medical tools, mobile phones and devices that use radio
