Question 1

What is Ohm's Law?

Accepted Answer

Ohm's Law states that Voltage (V) = Current (I) × Resistance (R). It describes the relationship between voltage, current, and resistance in an electrical circuit.

Question 2

How do I calculate resistance?

Accepted Answer

Resistance (R) = Voltage (V) ÷ Current (I). Enter the voltage in volts and current in amperes to find resistance in ohms.

Question 3

What units are used?

Accepted Answer

Voltage is measured in Volts (V), Current in Amperes (A), and Resistance in Ohms (Ω). Power is measured in Watts (W).
