Circuit analysis basics:

  • Method for determining voltage, current, and power
  • Based on fundamental electrical laws
  • Essential for designing and troubleshooting circuits
  • Applies to both DC and AC circuits
  • Used by electrical engineers and technicians

Key parameters:

  • Voltage (V): Electrical potential difference
  • Current (I): Flow of electric charge
  • Resistance (R): Opposition to current flow
  • Power (P): Rate of energy conversion

Ohm's Law:

Voltage: V = I × R

Current: I = V / R

Resistance: R = V / I

Power Formulas:

Power (using V and I): P = V × I

Power (using I and R): P = I² × R

Power (using V and R): P = V² / R

Circuit Combinations:

Series Resistance: R_total = R₁ + R₂ + ... + Rₙ

Parallel Resistance: 1/R_total = 1/R₁ + 1/R₂ + ... + 1/Rₙ

What is Circuit Analysis?

Circuit analysis is the process of studying electrical circuits to determine the electrical quantities like voltage, current, resistance, and power. It's a fundamental skill in electrical engineering that relies on principles like Ohm's Law and Kirchhoff's Laws.

Understanding circuit analysis allows engineers and technicians to design, troubleshoot, and optimize electrical systems. From simple DC circuits to complex AC networks, the same basic principles apply, though the mathematical methods may become more sophisticated.

The tools provided in this calculator cover the most common circuit analysis needs: Ohm's Law calculations for basic voltage-current-resistance relationships, power calculations, and series/parallel circuit analysis for determining equivalent resistance and current distribution.
