In a series circuit, which statement is true regarding the resistance and current flow?

In a series circuit, the total resistance is the sum of the individual resistances because in this configuration, the current has only one path to travel through. Therefore, each resistor adds to the total resistance encountered by the current.

As the current flows through the series of resistors, it experiences a cumulative effect, which means if you add the resistance values of each component, you determine the total resistance the current must overcome. This property is crucial for calculating total current using Ohm’s Law, where total voltage is divided by total resistance to find the current flowing through the circuit.

In contrast, the highest individual resistance would not reflect the total resistance in the circuit, as it overlooks the contributions from the other resistors. Additionally, the current in a series circuit remains constant throughout; it does not vary in different parts since there is only one path for it to follow. Lastly, the current flow being zero would only occur if there was a break in the circuit or if the voltage supply was removed, which is not the typical behavior of a functioning series circuit.
