Tera – 10¹², Giga – 10⁹, Mega – 10⁶.
Due to the fact that it can be expressed as positive or negative, charge is bipolar.
P > 0 means +ve Power Being delivered,P < 0 means –ve Power Being extracted.
There are four different categories of dependent sources. Current-controlled current/voltage sources and voltage-controlled current/voltage sources.
Current-controlled voltage source, or ICVS. Since voltage depends on current, it can be said that current is the controller and voltage is the dependent source (va=βia).
Voltage and current are equivalent in series.
The symbol used for representing independent sources in electrical circuit diagrams is a circle. Independent sources are voltage sources or current sources that provide a fixed value of voltage or current regardless of the rest of the circuit's conditions. In circuit diagrams, an independent voltage source is represented by a circle with a plus sign (+) inside, while an independent current source is represented by a circle with an arrow inside. These symbols indicate that the source provides a specific, constant value of voltage or current independently of the rest of the circuit's elements.
The candela, represented by the symbol cd, is the unit for luminous intensity.
In a parallel circuit, multiple components or loads are connected across the same two points or nodes. Each branch in the parallel circuit provides a separate path for the current to flow from the common point. The key characteristic of parallel circuits is that the voltage across all branches is the same (equal to the source voltage).
Resistance is the ability of a material to oppose a current flow.
The seven established quantities—length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity—are the foundation of the SI units.
A dependent voltage/current source is a type of source in electrical circuit analysis that is controlled by the voltage or current in another part of the circuit. Its value is determined by the voltage or current in a different component of the same circuit. This makes it different from an independent source, which provides a fixed value of voltage or current regardless of the rest of the circuit's conditions.
Dependent sources are also referred to as controlled sources since they are under the control of other circuit components.
Current differs from voltage when running in parallel.
The Superposition Principle is followed by a linear system. The parameters of a linear network are fixed, i.e., they don't change with voltage and current.
It is a passive element, which means it cannot produce electricity.
