Ohm's Law is a law of constant proportionality, and only applies to circuits in which the ratio of voltage to current is a constant over variations in applied voltage. Such circuits are called linear or ohmic circuits, and include most metals. However, in the case of metals such as tungsten, for electronic devices such as diodes, and for electrolytes, Ohm's Law does NOT apply, and we call such circuits 'non-linear' or 'non-ohmic'. For linear circuits, Ohm's Law simply states that the current flowing through that circuit is directly proportional to the voltage applied across its ends. The equation R = V/I is not, as many think, derived from Ohm's Law, but from the definition of the ohm.

Resistance in a circuit and in ohms law is represented by the letter?

The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.


If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60v the current flowingthrough the circuit is?

Ohms law states E=I*R. Isolating I we get, I = E/R.I = 60V/12ohms = 5 amps.


What are linear and nonlinear circuits?

Linear (Straight) circuit: An electronic circuit where the info sinusoidal flood of recurrence f give a stead state yield. This circuit take after ohms law and the estimation of electronic parts doesn't change with the level of voltage of current in the circuit. Non-Linear (Non direct) circuit: The circuit in which the parameters change as for current and voltage. The parameter esteem like resistance, capacitance, inductance, waveform, recurrence and so on, is not consistent. This circuit doesn't take after ohms law and the v-i attributes are not a straight line.


What is the resistance of the circuit in ohms?

The resistance of the circuit is measured in ohms.


If voltage is 12 volts and ohms is 0.5 how many amps in circuit?

Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps


Using ohm's law what is the formula to find the resistance in a circuit?
