Frequently Asked Questions
What is Ohm Law?
Ohm Law states that voltage equals current multiplied by resistance, describing the fundamental relationship between these three electrical quantities in a simple resistive circuit.
What is the difference between voltage and current?
Voltage is the electrical potential difference driving current flow, measured in volts, while current is the actual rate of electric charge flow through the circuit, measured in amperes.
Does Ohm Law apply to all electronic components?
Ohm Law applies precisely to ideal resistors and many simple components, but non-linear components like diodes and transistors do not follow a simple constant resistance relationship across all operating conditions.
