what is the principle of ohms ?
Answers
Hey mate:
here's your answer:
the ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.
Ohm’s law remains perfectly valid in alternating current. We need to include the time variable as follows:
V(t) = i(t) x R
in principle, this is very easy: all we have to do is connect the resistors that make up the circuit like we do in the case of DC, use the function generator instead of the power supply (DC power) and select AC on the multimeter when measuring the voltage and current of a circuit.
When AC is selected on the tester, then the value obtained is in Vrms or Vef, i.e. effective volts.
i hope it will be helpful to you
