Ohm's Law

- states that the current that flows in a circuit is directly proportional to the voltage and inversely proportional to the resistance. - is a basic but very useful law which is widely used from beginners to engineers to calculate current, voltage and resistance. - establishes the relationship between voltage, current and resistance in a circuit. This law states that the amount of current flowing in a circuit depends upon the amount of voltage in the circuit and the amount of resistance in the circuit.

-is the flow of electrons through a conductor. It is measured in Amps. The letter "I" is used to represent current. -Basically, Ohm's Law states that the current that flows in a circuit is directly proportional to the voltage and inversely proportional to the resistance. -the current in the circuit is directly proportional to the voltage in the circuit. -Which means when the voltage increases the current increases and when the resistance increases the current decreases.

is the force or electric pressure that allows current flow. It is measured in volts. The letter "V" (or sometimes "E") is used to represent voltage. As the voltage applied to a circuit increases, the current that flows through the circuit also increases A larger voltage will produce a larger current, a smaller voltage will produce a smaller current.

are the three parameters found in every electronic circuit no matter how simple or complex they are. Ohm's law establishes the relationship between these three parameters. In the simple circuit these three elements are present. The battery supplies the voltage (V), the resistor and the wires have resistance (R), and there is a current (I) that flows through the circuit as a result of voltage from the battery.

is the opposition to current flow. It is measured in ohms (?). The letter "R" is used to represent resistance. As we increase the resistance in a circuit, the current decreases

Resistance is the opposition to current flow or the resistance that a material presents to the flow of electric current through it. Good conductors such as gold, copper, and silver have low resistance and good insulators such as porcelain, glass, and plastic have high resistance. Resistance is measured in ohms (?). The letter "R" is used to represent resistance.
