## What are dependent current sources?

A dependent source is a current or voltage source whose value is not fixed (i.e., independent) but rather which depends on some other circuit current or voltage. The general form for the value of a dependent source is Y=kX where X and Y are currents and/or voltages and k is the proportionality factor.

## Do resistors affect current in a series circuit?

If you now add a resistor in series into this circuit – the current of the circuit will be smaller. So yes, the resistor does reduce the current.

## What is the difference between dependent source and independent source?

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.

## Can two current sources be connected in series?

Current sources are not allowed to be connected together in series, either of the same value or ones with different values. Also, another reason why series connected sources are not allowed for circuit analysis techniques is that they may not supply the same current in the same direction.

## Is current the same in series?

Current in series circuits The current is the same everywhere in a series circuit. It does not matter where you put the ammeter, it will give you the same reading.

## Is current constant in series?

In a series circuit, current is constant. Current will remain constant in a series circuit because of the principle of conservation of charge, which…

## Does a dependent current source have a voltage?

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. Dependent sources are useful, for example, in modelling the behavior of amplifiers.

## What is the ideal current source?

An ideal current source is by definition a two-terminal element with the property that the current flowing through the device is specified at every instant in time. This current does not depend on the voltage across the source.

## How are resistors in series connected to a voltage source?

shows resistors in series connected to a voltage source. The total resistance in the circuit is equal to the sum of the individual resistances, since the current has to pass through each resistor in sequence through the circuit.

## Is the current source of a circuit independent or dependent?

As with voltage sources, the current source can be either independent (ideal) or dependent (controlled) by a voltage or current elsewhere in the circuit, which itself can be constant or time-varying.

## How is the voltage drop across a resistor calculated?

According to Ohm’s law, the voltage drop, V, across a resistor when a current flows through it is calculated using the equation V = IR, where I equals the current in amps (A) and R is the resistance in ohms (Ω). Another way to think of this is that V is the voltage necessary to make a current I flow through a resistance R.

## Is the internal resistance the same as the current source?

The internal resistance (R P) produces the same effect as a resistance connected in parallel (shunt) with the current source as shown. Remember that circuit elements in parallel have exactly the same voltage drop across them.
