Simple DC Networks topics include: Series circuits, parallel networks, power, energy, resistivity, temperature coefficient, kirchhoffs current and voltage laws. A simple DC network is a direct-current (DC) circuit that consists of a current source and one or more loads. The current source can be a battery, and the loads can be circuit elements like light bulbs and electric motors. DC circuits are mostly used for simple applications. In a DC circuit, the current flows in only one direction, from the positive terminal to the negative terminal. There are two types of DC networks: active and...

A simple DC network is a direct-current (DC) circuit that consists of a current source and one or more loads. The current source can be a battery, and the loads can be circuit elements like light bulbs and electric motors. DC circuits are mostly used for simple applications. In a DC circuit, the current flows in only one direction, from the positive terminal to the negative terminal. There are two types of DC networks: active and passive. An active network contains one or more sources of supply, while a passive network does not contain any source of supply voltage or current. Some sources of DC current include: Primary cell (zinc-carbon dry cell) Rechargeable secondary cell (lead-acid cell) Hydrogen fuel cell Nickel-cadmium cell Kirchhoff's current and voltage laws quantify how current flows through a circuit and how voltage varies around a loop in a circuit. Kirchhoff's current law states that the current entering a junction must equal the current leaving a junction. This is a consequence of charge conservation. Kirchhoff's voltage law states that the change in potential around a closed loop must be zero. The formula for voltage rule is V = IR, where: V: is the voltage difference I: is current in the loop R: is the resistance of the circuit element in ohms Gustav Robert Kirchhoff (1824-1887) formulated the Laws of Closed Electric Circuits in 1845. These laws are now known as Kirchhoff's Voltage and Current Laws. Show less
