## AQA GCSE Series Circuit

**Series Circuit**

**A series circuit** is a **single loop circuit, **and the **components **are** connected **along a** single path, end to end.**

Above is an example of a **series** circuit with **two bulbs.**

**Series Circuit Rules**

**Rule 1: In a series circuit, the current is the same at all points. **

In the **above circuit** the current is at **5 Amps** at all **3 ammeters**.

**Rule 2:** In a **series circuit** the **potential difference** is **shared** between the **components**.

In the **above circuit**, the **10V potential difference** across the cell is **shared** between the two bulbs **equally**. So the **potential difference across** each **bulb** is **5V**.

**Rule 3:** The **total resistance** in a **series circuit** is the **sum** of the **individual resistors. **

** **

In the **above circuit, **there are** two 5 ohm resistors.** So, the** total resistance** is** 10 ohms. **

**Practice Questions**

1.State the value for the **current** for **ammeter A _{1}** in the circuit below:

2. Calculate the potential difference across the cell for voltmeter V_{1}, using the cell diagram below.

3. The total resistance of a series circuit is 35 ohms. There are 3 resistors in series, that each have their own resistance value in the ratio of 4:2:1. Calculate the resistance of each resistor.
