Voltages in Series

Series circuit or series connection means when two or further electrical components are linked together in a chain like arrangement within a circuit. In this kind of circuit, there is only a single way for the charge to pass throughout the external circuit. The potential variation in charge across two points in an electrical circuit … Read more

Voltage Regulators

In electrical circuits, we sometimes need a stable voltage across a particular load. The voltage across the load should not vary due to changes in the input voltage or due to the load itself. For such applications, we need a voltage regulator. Today we are going into the nitty gritty of voltage regulators and we … Read more

Regulated Power Supply

Today almost every electronic device needs a DC supply for its smooth operation and they need to be operated within certain power supply limits. This required DC voltage or DC supply is derived from single phase ac mains. A regulated power supply can convert unregulated an AC (alternating current or voltage) to a constant DC … Read more

Voltage Regulator

The voltage regulator is simply an electronic or electrical device which can sustain the voltage of a power supply within suitable limits. The electrical equipments connected to the voltage source should bear the value of the voltage. So, the source voltage should be in a certain range which is acceptable for the connected equipments. This … Read more

Voltage Follower

Voltage follower is an Op-amp circuit whose output voltage straight away follows the input voltage. That is output voltage is equivalent to the input voltage. Op-amp circuit does not provide any amplification. Thus, voltage gain is equal to 1. They are similar to discrete emitter follower. The other names of voltage follower are Isolation Amplifier, … Read more

Voltage Multiplier

It is in actuality a modified capacitor filter circuit (rectifier circuit) which makes a DC output voltage that is two or more than two times the AC peak input. In this section, we can look into full-wave voltage doubler, half-wave voltage doubler, voltage tripler and finally quadrupler. Half Wave Voltage Doubler The input wave form, … Read more

Voltage Source

As an introduction, we can go through the Electrical source. It is nothing but a device which can deliver electric power to a connected circuit. They can be a Current source or a Voltage source. Here, we can discuss about the voltage source which is most commonly used. Voltage source is in fact a passive … Read more

Voltage to Current Converter

The circuits in instrumentation for analog representation of certain physical quantities (weight, pressure, motion etc), DC current is preferred. This is because DC current signals will be constant throughout the circuit in series from the source to the load. The current sensing instruments also have the advantage of less noise. So, sometimes it is essential … Read more

Voltage Regulator 7805

All voltage sources cannot able to give fixed output due to fluctuations in the circuit. For getting constant and steady output, the voltage regulators are implemented. The integrated circuits which are used for the regulation of voltage are termed as voltage regulator ICs. Here, we can discuss about IC 7805. The voltage regulator IC 7805 … Read more

Voltage Doubler

Voltage doubler, as the name indicates it can deliver the output voltage which is double as that of the input voltage. It is a voltage multiplier with the voltage multiplication factor equal to 2. The circuit is formed by an oscillating AC input voltage, two capacitors and two diodes. The input is AC voltage and … Read more
