RL Series Circuit Analysis

When a resistive-inductive (RL) series circuit has its supply voltage switched on, the inductance produces an initial maximum level of counter-emf that gradually falls to zero. The circuit current is zero initially and grows gradually to its maximum level. The behavior of an RL series circuit is most easily understood …

Superposition Theorem

Superposition theorem is stated as follows: The current is any circuit element or voltage across any element of a linear bilateral network is the algebraic sum of the currents or voltages separately produced by each source of energy. Simultaneous equations may be avoided in the solution of a complex network …

Metric Units of Measurement SI Units

SI units are most widely used units of measurement belong to an international system of units which is also known as SI or Metric System. SI comprises of three main categories which are prefixes, base units and derived units. SI base units are seven which are defined as; Length (Meter) …
