Electronics Calculators – Ohm's Law & Power

Choose this endpoint when you need to solve any Ohm's law or electrical power equation given exactly two of the four fundamental quantities (V, I, R, P). It is purpose-built for electronics calculations and returns all four values plus engineering-formatted strings in one call, making it ideal for circuit design checks, component selection, and educational explanations — without requiring a general-purpose math or code-execution engine.

• Fewer than two query parameters provided — cannot solve the system with only one known
• Conflicting or physically impossible values (e.g. negative resistance) may produce null outputs or error reasons
• Zero-value inputs that cause division by zero are flagged in the reasons array
• Missing required 'input' wrapper causes schema validation error
