# What is the difference between voltage source and current source?

## What is the difference between voltage source and current source?

In other words, the source is an active network element meant for generating electrical energy. The various types of sources available in the electrical network are voltage source and current sources. A voltage source has a forcing function of emf whereas the current source has a forcing function of current.

### What is a current source amplifier?

This is a fancy name for a power current source. An input voltage causes the amplifier to deliver a proportional output current. Of course this same sort of thing would occur with an ordinary amplifier driving a pure resistance but a loudspeaker circuit is not purely resistive.

#### Is a voltage source also a current source?

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.

**How many volts should my amp be?**

Usually the range is somewhere between 10.5-16.5 volts.

**Can voltage source and current source in series?**

The simplest non-ideal current source consists of a voltage source in series with a resistor. The amount of current available from such a source is given by the ratio of the voltage across the voltage source to the resistance of the resistor (Ohm’s law; I = V/R).

## What are examples of voltage sources?

Nuclear, coal, natural gas, hydroelectric and wind power all use generators to generate voltage.

### Why current source is connected in parallel?

When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them.

#### Do voltage sources increase current?

In the case of all real or practical voltage sources, this internal resistance, RS no matter how small has an effect on the I-V characteristic of the source as the terminal voltage falls off with an increase in load current. This is because the same load current flows through RS.

**Are audio amplifiers AC or DC?**

Amplifiers require a DC (sometimes called rail) voltage to provide a constant power source which the amplifier can in turn use to amplify the input signal.

**How many amps does a 500 watt amplifier draw?**

4.17 Amps

In short, 500 Watts equals 4.17 Amps.

## Can two current sources be connected in parallel?

You can’t connect two ideal current source in series or two ideal voltage source in parallel if their rated current or voltage are not same.

### How is a current source AMP different from a voltage source amplifier?

A current source amp is an amplifier whose output impedance is significantly higher than that of the load and so makes constant current regardless of load. This is not a tube or solid state amp in particular; to achieve this, the amp must employ current feedback, which is a bit different from voltage (traditional) feedback.

#### Which is better a voltage or a current source?

The Magnepans don’t have them so need a lot more current for the low frequencies. Ideal voltage source provides voltage that is independent of the load. Power delivered will be inversely proportional to load impedance. Ideal current source provides current that is independent of the load.

**Can a current source be turned on without a load?**

Any voltage controlled current source should never be turned on without a load, (with some impedance, real or effective) connected to its output terminals. When asked to operate in this way, any current source (including an AE Techron amplifier) will increase its output voltage in an attempt to drive the requested current into the load.

**Which is more current 5 V or 10 V?**

To put this in practical terms, if a 5 V source and a 10 V source are connected to two identical circuits, the 10 V source propels electric charge with twice as much energy and consequently will produce twice as much current. When a voltage source symbol appears in a schematic, it represents an i deal voltage source.
