Frequently Asked Questions
What is Ohm's Law?
Ohm's law states that electrical current (I) flowing through a conductor is directly proportional to voltage (V) and inversely proportional to resistance (R): V = I × R.
How is electrical power calculated in Watts?
Electrical Power (P) in Watts is calculated by multiplying Voltage (V) by Current (I): P = V × I = I² × R.
