How are voltage and current distributed in series circuits?
1 Answer
In a series circuit, components are connected one after the other in a single path such that there is only one route for the current to flow. This creates a consistent flow of current throughout the circuit. The distribution of voltage and current in a series circuit follows these rules:
Current (I): The same current flows through all the components in a series circuit. This is because there is only one path for the current to travel, so the current remains constant throughout the circuit.
Voltage (V): The voltage across the entire circuit is divided among the components. In other words, the total voltage supplied by the power source is distributed across each component in the series.
Voltage Sum: The sum of the individual voltage drops across each component in a series circuit equals the total voltage supplied by the power source. This is a consequence of the conservation of energy.
Mathematically, the relationships can be summarized as follows:
Total Voltage (V_total) = Voltage across Component 1 + Voltage across Component 2 + ... + Voltage across Component N
Total Current (I_total) = Current through Component 1 = Current through Component 2 = ... = Current through Component N
It's important to note that the current remains the same throughout a series circuit, but the voltage is shared among the components. This has implications for the behavior of devices connected in series. For instance, if you have a series of resistors, the total resistance (R_total) is the sum of the individual resistances (R1 + R2 + ... + RN). Similarly, if you have series-connected light bulbs, the brightness of each bulb will be affected by the total voltage applied to the circuit and the resistance of each bulb.
In summary, in a series circuit, the current remains constant throughout, and the voltage is distributed among the components according to their individual resistances or impedance.
