Understanding of series and parallel resistors

-
  In an electrical circuit, resistors can be connected in series or in parallel. The connection determines how the resistors behave and how they affect the current and voltage in the circuit. In a series connection, the resistors are connected end-to-end, so that the current flows through each resistor in turn. In a parallel connection, the resistors are connected side-by-side, so that the current can flow through multiple resistors at the same time. The relationship between the resistance, current, and voltage in a circuit with resistors connected in series is given by Ohm's law: V = IR Where V is the voltage across the resistors, I is the current through the resistors, and R is the total resistance of the circuit. The total resistance of a circuit with resistors connected in series is equal to the sum of the individual resistances: R = R1 + R2 + R3 + ... The relationship between the resistance, current, and voltage in a circuit with resistors connected in parallel i...

Understanding of independent and dependent sources

-
  In an electrical circuit, a source is a device that provides electrical energy to the circuit. Sources can be classified as either independent or dependent. An independent source is a source that can produce an electric potential (voltage) or an electric current without being influenced by the circuit. Examples of independent sources include batteries, generators, and power supplies. A dependent source is a source that produces an electric potential or an electric current based on the voltage or current in the circuit. Examples of dependent sources include transistors and thermocouples. The behavior of a circuit with an independent source is determined by the characteristics of the source and the resistive elements in the circuit. The circuit will operate the same way regardless of the current or voltage in the circuit. The behavior of a circuit with a dependent source is more complex, as the source produces a current or voltage that is dependent on the current or voltage...

Understanding of impedance, admittance, active power, reactive power, apparent power, average power, instantaneous power, and power factor

-
  In an alternating current (AC) circuit, the electrical quantities of interest include the impedance, admittance, active power, reactive power, apparent power, complex power, average power, instantaneous power, and power factor. Impedance is a measure of the opposition to the flow of AC current in a circuit. It is represented by the symbol Z and is expressed in units of ohms. Impedance is a complex quantity, meaning that it has both a real and an imaginary component. The real component is known as the resistance and the imaginary component is known as the reactance. Admittance is the reciprocal of impedance and is a measure of the ease of AC current flow in a circuit. It is represented by the symbol Y and is expressed in units of siemens. Admittance is also a complex quantity, with a real component known as the conductance and an imaginary component known as the susceptance. Active power is the rate at which electrical energy is transferred in an AC circuit. It is the produc...
