Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Provided the temperature remains constant, the resistance R of the conductor is a constant, and thus the current I is directly proportional to the voltage V, and the ratio V/I is constant. This ratio is called the resistance, and it is the resistance of the conductor between the two points.

##### What are the 3 formulas in Ohm's law?

1. Voltage (V) = Current (I) x Resistance (R)

2. Current (I) = Voltage (V) / Resistance (R)

3. Resistance (R) = Voltage (V) / Current (I) What is the basic Ohm's law formula? The basic Ohm's law formula is V = IR, where V is voltage, I is current, and R is resistance. This formula can be used to calculate any of the three quantities if the other two are known.

##### What is Ohm's first law?

Ohm's first law states that the current through a conductor is proportional to the potential difference across the conductor. The law is named after Georg Ohm, who, in a paper published in 1827, described experiments investigating the relationship between the current flowing through a circuit and the voltage applied to the circuit. What is the SI unit of Ohm's law? The SI unit of Ohm's law is the volt.

##### How do you explain ohms?

Ohm's law is one of the most fundamental equations in electronics. It states that the current through a conductor is proportional to the potential difference (voltage) across it. The constant of proportionality is called the resistance, and is measured in ohms.

In practical terms, this means that if you have a device that is designed to operate at a certain voltage, you can calculate the maximum current it can draw by using the following formula:

I = V/R

Where I is the current in amps, V is the voltage in volts, and R is the resistance in ohms.

This equation is named after German physicist Georg Ohm, who first published it in 1827.
