# Is a battery a voltage source or a current source?

## Is a battery a voltage source or a current source?

A battery is a voltage source, not a current source. Some terminology: what you attach across a source is often referred to as a “load”. Ideal sources are independent of load.

What is the voltage across a current source?

Voltage sources The voltage across an ideal voltage source is independent of the current flowing through it. An ideal voltage source can be defined by an equation like this: v = V v = \text V v=Vv, equals, start text, V, end text, for example: v = 1.5 V v = 1.5\,\text V v=1.

### How do you convert voltage source to current source?

So here we will apply voltage-to-current source transformation, which is very similar to current-to-voltage source transformation. 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.

Is a current source a DC source?

For an AC analysis, DC sources are short circuit (voltage source) or open circuit (current source), respectively. Accordingly, for a DC analysis, AC sources are short circuit (voltage source) or open circuit (current source), respectively.

An ideal current source is a device that always produces the given current regardless of what voltage is applied across it. A device that always has 0 V across it is called a 0 V voltage source, or, less formally, a short circuit.

## 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. The voltage will be determined solely by the circuit elements which are connected to this source and it can be computed according to the rules which we will learn in

Can an ideal current source have zero voltage?

The internal resistance of an ideal current source is infinite. An independent current source with zero current is identical to an ideal open circuit. The voltage across an ideal current source is completely determined by the circuit it is connected to. When connected to a short circuit, there is zero voltage and thus zero power delivered.

### Can power supply be used as a current source?

The quick answer to this question is, yes, most standard DC power supplies can be used as current sources. However, this question deserves more attention, so what follows is the longer answer. Most DC power supplies can operate in constant voltage (CV) or constant current (CC) mode.
