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.
The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.
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.
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
Ohms law is E=IxR. Kirkoffs law has to do with the distribution of voltage and amperes. The amperes in a series circuit is always the same and the voltage changes. In a parallel circuit the voltage is always the same but the amperes change. You can find all the values in a circuit with limited information using these two laws.
The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.
Ohms law states E=I*R. Isolating I we get, I = E/R.I = 60V/12ohms = 5 amps.

The resistance of the circuit is measured in ohms.
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
Ohms Law
ohms law use kirchoff's voltage law around the loop
The resistance of the circuit is measured in units of ohms.
use ohms law which in this case is volts divided by resistance in circuit
5 Ohms Ohm's Law is V=I*R, 40V=8A*R, R=5 ohms.
In a 12VDC circuit with a 1K load, there will be 12ma of current. (Ohm's law: Volts = Amps * Ohms, so Amps = Volts / Ohms.)
