Describe the behaviour of current, voltage, and resistance in a series circuit. Explain why the current remains the same throughout the circuit and how the total resistance is calculated.
In a series circuit, the current passing through each component is the same. This is because there is only one path for the current to flow, and the current encounters the same resistance in each component. According to Ohm's Law (V = IR), the voltage across each component is directly proportional to its resistance. As a result, the total voltage of the circuit is divided among the components based on their resistances.
The total resistance in a series circuit is calculated by summing up the individual resistances of each component. This is because the total resistance is equivalent to the cumulative effect of all the resistances encountered by the current in the circuit.
