Electrical Engineering
Electric Power Law (P = V × I)
Power (Watts) = Voltage (Volts) × Current (Amperes)

Flow of electric charge
💡 What This Is Useful For: Sizing household circuit breakers, selecting resistor power ratings to prevent heat failure, calculating EV charger draw, and designing solar battery banks.
📐 Real-World Worked Example: A 120 V household circuit powering a 1500 W space heater draws: I = 1500 / 120 = 12.5 Amperes. (Requires a standard 15A or 20A breaker).
Electrical Engineering
Ohm’s Law (V = I × R)

💡 What This Is Useful For: Designing printed circuit boards (PCBs), choosing current-limiting resistors for LEDs, and testing automotive sensors.
📐 Real-World Worked Example: To power a 2.0 V, 20 mA (0.02 A) red LED from a 5.0 V microcontroller pin: Required voltage drop is 5 - 2 = 3 V. Resistor R = 3 / 0.02 = 150 Ohms.
