1. Series And Circuits

2. Series circuits
The current has only one loop to flow through. Series circuits are used in flashlights and some holidays and the voltage across the circuit is the sum of the voltages across each component.

3. The brightness gets higher as each bulb is added
The brightness gets higher as each bulb is added . A circuit is a complete path around which electricity can flow

4. About
How many electrical such as lights, clocks,stereos and televisions do you see that are plugged into electrical outlets?. Circuits include three components. One is a source of voltage difference that can be provide by a battery. Another is one or more devices that use electrical . Circuits also include conductors such as wires that connect to the voltage

5. Difference between series and parallel circuits
In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component
