One can not complete an electronics circuit without current or voltage sources. In this video, You will find a detailed concept of an ideal voltage source and ideal current source.

Ideal Voltage Source: Ideal voltage sources maintain the constant voltage independent of load resistance or current.
The internal resistance of the Ideal voltage source is zero.

Ideal Current Source: Ideal current sources deliver a constant current independent of load resistance.
The internal resistance of the Ideal current source is infinite.
