what is ohm's law ¿?
Answers
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.
Answer:
the law that for any circuit the electric current is directly proportional to the voltage and is inversely proportional to the resistance.
Explanation:
Ohm's law describes the way current flows through a resistance when a different electric potential (voltage) is applied at each end of the resistance. ... More water will flow through the pipe (current) the more pressure is applied (voltage) and the bigger the pipe is (lower the resistance).

To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists.
E = I x R
When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.
Named for German physicist George Ohm (1789-1854), Ohm's Law addresses the key quantities at work in circuits:
