FAQ
Frequently asked questions
What is Ohm's Law?
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The formula is V = I × R.
What does V, I, and R stand for?
V stands for Voltage (measured in Volts), I stands for Current (measured in Amperes), and R stands for Resistance (measured in Ohms).
How do I calculate Resistance?
Rearranging Ohm's Law, Resistance (R) can be calculated by dividing Voltage (V) by Current (I). So, R = V / I.
