Circuit Analysis

Circuit Analysis

• Series Circuit: A circuit with components connected one after the other, forming a single loop.
  • Current flows through each component in sequence.
  • Total resistance is the sum of individual resistances.
• Parallel Circuit: A circuit with components connected between the same two points, forming multiple branches.
  • Current divides among branches, with each branch having the same voltage.
  • Total resistance is less than the smallest individual resistance.
• Short Circuit: A circuit with an unintended path of low resistance, causing excessive current flow.
• Open Circuit: A circuit with a broken or disconnected path, preventing current flow.

Ohm's Law

• Ohm's Law: The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R
• Conductance: The reciprocal of resistance (1/R), measuring how easily current flows through a material.
• Power: The rate of energy transfer (P) in a circuit, calculated by P = V × I.

Voltage and Resistance

• Voltage: The potential difference between two points in a circuit, measured in volts (V).
• Resistance: The opposition to current flow in a circuit, measured in ohms (Ω).
• Voltage Drop: The decrease in voltage across a component or circuit section.
• Voltage Source: A device providing a stable voltage output, such as a battery.

Electrical Circuits

• Circuit Components: Devices that make up a circuit, including:
  • Resistors: Devices that oppose current flow, with a fixed resistance value.
  • Capacitors: Devices that store energy, with a fixed capacitance value.
  • Inductors: Devices that store energy in a magnetic field, with a fixed inductance value.
• Circuit Configuration: The arrangement of components in a circuit, including series, parallel, and series-parallel combinations.

Electric Current

• Electric Current: The flow of electrons through a conductor, measured in amperes (A).
• Current Flow: The direction of current flow, from positive to negative terminals.
• Current Density: The amount of current flowing through a given area, measured in amperes per square meter (A/m²).
• Conventional Current: The flow of positive charge carriers, such as holes in a semiconductor, opposite to the flow of electrons.
