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. When all the devices are connected using series connections, the circuit is referred to as a series circuit. 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. Each charge passing through the loop of the external circuit will pass through each resistor in consecutive fashion. A short comparison and contrast between series and parallel circuits was made in the previous section of Lesson 4. 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. 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.

Total current is determined by the voltage of the power supply and the equivalent resistance of the circuit. Verify your calculations by adding the voltage drops. On a series circuit they should equal the voltage increase of the power supply. There are three equations for determining power. Since we have three resistors, let's apply a different equation to each as an exercise. Note: we'll answer part iv before part iii.

In Grade 10 and Grade 11 you learnt about electric circuits and we introduced three quantities which are fundamental to dealing with electric circuits. These quantities are closely related and are current, voltage potential difference and resistance. To recap:. Charge moving through a battery gains energy which is then lost moving through the circuit. Work must be done for a charge to move through a resistor.

## Resistors in Circuits

Most circuits have more than one component, called a resistor that limits the flow of charge in the circuit. A measure of this limit on charge flow is called resistance. The simplest combinations of resistors are the series and parallel connections illustrated in [link]. The total resistance of a combination of resistors depends on both their individual values and how they are connected. Resistors in Series When are resistors in series? Resistors are in series whenever the flow of charge, called the current , must flow through devices sequentially.
