Questioning of fundamentals of current flow

[rohanprabhu]

Although i do understand how current is same in electrical components in series.. but why does the voltage remain constant in parallel?

Also since voltage remains constant in parallel, is that the reason change in voltage is generally chosen as the signal in digital circuits?

Kirchhoff's Voltage/Loop Rule, which is a direct result of conservation of charge.

Current flow is a fundamental concept in electricity and it is important to question and understand its principles. In a series circuit, the same amount of current flows through each component because there is only one path for the current to take. This is due to the conservation of charge, where the total amount of charge entering a circuit must equal the total amount of charge exiting the circuit.

In a parallel circuit, the current is divided among multiple paths, but the total amount of current entering the circuit must still equal the total amount of current exiting the circuit. This means that the current in each individual path may be different, but the overall current remains the same.

As for the voltage remaining constant in parallel, this is due to the principle of voltage division. In a parallel circuit, the voltage across each component is the same as the voltage across the entire circuit. This is because the voltage source is shared among the different paths, and the total voltage drop across the circuit must equal the voltage of the source.

In digital circuits, the change in voltage is chosen as the signal because it allows for easier and more precise control of the flow of current. By using a specific voltage level to represent a 1 or a 0, digital circuits can accurately process and transmit information. Additionally, using a constant voltage level in parallel circuits helps to ensure that the signal remains strong and consistent throughout the circuit.
