The actual amount of current varies inversely with the amount of overall resistance. The current is no greater at one location as it is at another location. This increased resistance serves to reduce the rate at which charge flows (also known as the current).Ĭharge flows together through the external circuit at a rate that is everywhere the same. Since there is only one pathway through the circuit, every charge encounters the resistance of every device so adding more devices results in more overall resistance. In that section, it was emphasized that the act of adding more resistors to a series circuit results in the rather expected result of having more overall resistance. Each charge passing through the loop of the external circuit will pass through each resistor in consecutive fashion.Ī short comparison and contrast between series and parallel circuits was made in the previous section of Lesson 4. In a series circuit, each device is connected in a manner such that there is only one pathway by which charge can traverse the external circuit. When all the devices are connected using series connections, the circuit is referred to as a series circuit. ![]() As mentioned in the previous section of Lesson 4, two or more electrical devices in a circuit can be connected by series connections or by parallel connections.
