What are independent and dependent sources?

Independent source are those, whose value of either the voltage or the current to be delivered is independent of any other parameter of the network. Where as the dependent sources are those, whose value of either the voltage or the current to be delivered is dependent or controlled on other parameters of the network.

What are independent sources in electrical circuits?

Independent voltage sources supply a constant voltage that does not depend on any other quantity within the circuit. Ideal independent sources can be batteries, DC generators or time-varying AC voltage supplies from alternators.

What are the different types of dependent sources?

There are four possible dependent sources: the voltage-controlled voltage source (VCVS), the current-controlled voltage source (CCVS), the voltage-controlled current source (VCCS), and the current-controlled current source (CCCS).

What is the frequency of electricity?

50Hz
Electrical frequency is the measure of the rate of that oscillation and is measured in the number of changes per second – also called hertz (Hz). A generator running at 3,000 rpm, with two magnetic poles, produces electricity at a frequency of 50Hz.

What is a dependent source in a circuit?

In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. An operational amplifier can be described as a voltage source dependent on the differential input voltage between its input terminals.

What is dependent voltage in circuit?

The sources whose output voltage or current is not fixed but depends on the voltage or current in another part of the circuit is called Dependent or Controlled source.

What is a dependent source in circuit?

What is dependent voltage?

Dependent Voltage Source is a four terminal source whose output voltage is dependent on circuit current or voltage. Unlike ideal voltage source, the magnitude of voltage output of this source is not constant. Rather, it is linearly related to input current or voltage.

How many types of independent sources are there?

There are two principal types of source, namely voltage source and current source. Sources can be either independent or dependent upon some other quantities. An independent voltage source maintains a voltage (fixed or varying with time) which is not affected by any other quantity.

What is the relationship between current and frequency?

The waveform of a current describes the shape of one cycle of the current. The frequency of a current is how many times one cycle of the waveform is repeated per second, and is measured in hertz (Hz). Mains electricity has a sine waveform (Figure 2b) and a frequency of 50Hz, i.e. it repeats 50 times per second.

Where are dependent sources used?

Dependent sources are used to model transistors and the operational amplifier IC. A dependent source is a voltage or current source controlled by either a voltage or a current at the input side of the device model. The dependent source drives the output side of the circuit.
