## What is the relationship between current and voltage?

Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance.

## How are voltage and current sources represented?

Real voltage sources can be represented as ideal voltage sources in series with a resistance r, the ideal voltage source having zero resistance. Real current sources can be represented as ideal current sources in parallel with a resistance r, the ideal current source having infinite resistance.

How do you convert voltage source to current source?

The process involves replacing the voltage source V in series with a resistor R with an equivalent network which has a current source I=VR I = V R in parallel with a resistor R. The current source is oriented such that the arrow points towards the positive terminal of the voltage source being replaced (see Figure 4).

Does a voltage source have current?

A voltage source is a two-terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source.

### What is the relationship between the voltage of the dependent source and V?

Dependent Voltage Source Symbols Then the VCVS output voltage is determined by the following equation: VOUT = μVIN. Note that the multiplying constant μ is dimensionless as it is purely a scaling factor because μ = VOUT/VIN, so its units will be volts/volts.

### What is superposition theorem?

The superposition theorem states that a circuit with multiple voltage and current sources is equal to the sum of simplified circuits using just one of the sources.

How a voltage source can be converted into current source and vice versa?

When a voltage source is converted into the current source or vice versa using ohm’s law method is known as source conversion. V =IR, where, V= value of voltage source which is connected across the same two terminal in series with the same resistance, R = resistance and I = value of current source.

Do current sources increase voltage?

So in summary: In a voltage source the voltage is fixed and the current changes depending on the load. In a current source the current is fixed and the voltage changes depending on the load.

#### Does current source change voltage?

As its name implies, a current source is a circuit element that maintains a constant current flow regardless of the voltage developed across its terminals as this voltage is determined by other circuit elements.
