Explain the concepts of current, resistance, and voltage and their relationship through Ohm's Law. Current is the flow of electric charge in a circuit, measured in amperes (A), representing the rate at which charges pass through a specific point in the wire. Resistance is a property of materials that opposes the flow of electric current in a circuit, measured in ohms (Ω), and depends on the dimensions and resistivity of the material. Voltage is the electric potential difference between two points in a circuit and is measured in volts (V); it can be considered the force that pushes electric charges through a conductor. Ohm's Law defines the relationship between current, resistance, and voltage as I = V/R, where I is the current (A), V is the voltage (V), and R is the resistance (Ω). This equation shows that the current flowing through a conductor is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
