What is direct current?
Direct current (DC) is a type of electrical current where the flow of electricity always moves in one direction, unlike alternating current (AC), where the flow of electricity changes direction regularly.
In a direct current circuit, the current flows from positive to negative pole, and this direction remains unchanged over time. An example of this is a battery cell, where one end (positive pole) provides an excess of electrons, while the other end (negative pole) lacks electrons. When a circuit is closed, electrons move from the negative pole to the positive pole, creating a steady flow of electrons.
Direct current is commonly used in electronic devices such as battery-powered devices, solar panels, electric cars, and in other contexts where a constant flow of electricity is required.
