⚡ Ohm's & Kirchhoff's Master Calculator

🎯 Getting Started

Choose from four powerful calculators to analyze DC circuits:

• Ohm's Law: Solve for voltage (V), current (I), or resistance (R)
• Power Calculator: Calculate power using any two known values
• Voltage Divider: Find voltage drops across series resistors
• Current Divider: Calculate current distribution in parallel branches

📐 Unit Prefixes

The calculator automatically handles unit prefixes. You can enter values like:

• Voltage: 5V, 12V, 3.3V, 230V, 1.5kV
• Current: 2A, 500mA, 10µA (or 10uA), 1.5mA
• Resistance: 1kΩ, 10k, 4.7MΩ, 100Ω, 10mΩ
• Power: 25W, 500mW, 2kW

Supported prefixes: p (pico), n (nano), µ/u (micro), m (milli), k (kilo), M (mega)

⚠️ Case matters: lowercase 'm' = milli (10^-3), uppercase 'M' = mega (10⁶)

💡 Ohm's Law Formula

V = I × R

• V = Voltage (Volts)
• I = Current (Amperes)
• R = Resistance (Ohms)

This fundamental relationship describes how voltage, current, and resistance relate in electrical circuits.

⚡ Power Formulas

Power can be calculated using any two known values:

• P = V × I (Power = Voltage × Current)
• P = V² / R (Power = Voltage² / Resistance)
• P = I² × R (Power = Current² × Resistance)

🔌 Kirchhoff's Laws

Kirchhoff's Voltage Law (KVL): The sum of all voltages around a closed loop equals zero. This is the principle behind voltage dividers.

Kirchhoff's Current Law (KCL): The sum of all currents entering a node equals the sum of currents leaving. This is the principle behind current dividers.
