Ohm's Law is a fundamental principle in physics that describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current through a conductor is directly proportional to the voltage and inversely proportional to the resistance.
In series circuits, Ohm's Law states that the total resistance is equal to the sum of individual resistances. This means that the current is the same at all points in the circuit and the voltage is divided among the resistors.
In parallel circuits, Ohm's Law states that the total current is equal to the sum of individual currents. This means that the voltage is the same across all branches of the circuit and the total resistance is reduced.
Yes, it is possible to have a combination of series and parallel circuits in the same circuit. This is known as a series-parallel circuit and the same principles of Ohm's Law apply.
In series circuits, resistors add up, increasing the overall resistance. In parallel circuits, resistors decrease the overall resistance. Ohm's Law explains this behavior by showing the relationship between voltage, current, and resistance.
