Quick Reference. The ratio of the potential difference between the ends of a conductor to the current flowing through it is constant. This constant is the resistance of the conductor, i.e. V = IR, where V is the potential difference in volts, I is the current in amperes, and R is the resistance in ohms. The law was discovered in 1827 by Georg Ohm.

It's done so because to find resistance according to Ohm's law, we are dividing the voltage by current. So when we find the slope, which is. (Δy/Δx) of the straight-line graph (i.e., resistance), we need the voltage to be on the Y-axis (numerator of the fraction) and current on the X-axis (denominator). Hence, the other way round.

By putting the known values in the Ohm's law formula wheel: 24 volts / 6 ohms = 4 amps. Now you know the missing variable's value. You can use Ohm's law whenever you know two unit variables in the formula. Here's another example in which you have 200 volts and 20 amps: 200 volts / 20 amps = 10 ohms.
Physics Info
What is Ohm's Law? Electrical, Fundamentals. 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.

Ohm law is a relationship between three physical phenomena: current, voltage, and resistance. Current is defined as the flow of positive charge from a source to a negative charge source. The units for current are C/s for the amount of charge (C) that travels per unit time (s). The ampere (A) is the common unit of current equal to 1 C/s and the symbol for current is I. Current is an intrinsic.

The lightbulb filament violates Ohm's Law. Ohm's Law Statement: Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant. Ohm's Law Equation: V = IR, where V is the voltage across the conductor, I is the current.

Ohm's law states that. "the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them". Ohm's law can be expressed as. I = U / R (1)

Power [ P = V x I ] = 24 x 2 = 48W. Power within an electrical circuit is only present when BOTH voltage and current are present. For example, in an open-circuit condition, voltage is present but there is no current flow I = 0 (zero), therefore V*0 is 0 so the power dissipated within the circuit must also be 0.
