Explain Ohm’s law. Be sure to include the following vocabulary words in your explanation: Ohm’s Law, current, resistance, voltage, and circuit.
Ohm's Law is a fundamental principle in the field of electrical engineering that describes the relationship between current, voltage, and resistance in a circuit.
According to Ohm's Law, the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. In other words, the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R). The mathematical equation for Ohm's Law is written as:
I = V / R
Where:
- I represents the current flowing through the circuit in amperes (A)
- V represents the voltage applied across the circuit in volts (V)
- R represents the resistance of the circuit in ohms (Ω)
This equation can be rearranged to solve for any one of the three variables, given the other two. Ohm's Law is used to calculate the behavior of electrical circuits, helping engineers and technicians to determine the current, voltage, or resistance in a circuit when one of these quantities is known.
In summary, Ohm's Law states that the current in a circuit is directly related to the voltage applied and inversely related to the resistance of the circuit. This relationship is fundamental to understanding and analyzing the behavior of electrical circuits.
