## Study Notes

### Electricity and Batteries

#### Simple Circuits

• A simple circuit consists of:
• A power source (e.g., battery)
• Conductors (e.g., wires)
• A load (e.g., light bulb)
• Characteristics of a simple circuit:
• Closed loop: the circuit must be continuous for electricity to flow
• One way: electricity flows from the positive terminal of the power source, through the conductor, and back to the negative terminal
• Types of simple circuits:
• Series circuit: components are connected one after the other
• Parallel circuit: components are connected between the same two points

#### Energy Transfer

• Energy transfer in electric circuits:
• Electrical energy is converted into other forms of energy (e.g., light, heat, sound)
• Energy is transferred from the power source to the load
• Efficiency of energy transfer:
• Ideal efficiency: 100% (all electrical energy is converted to useful energy)
• Real-world efficiency: <100% (some energy is lost as heat, etc.)
• Factors affecting energy transfer:
• Resistance: opposes the flow of electricity, converting some energy into heat
• Voltage and current: affect the rate of energy transfer

### Simple Circuits

• A simple circuit consists of a power source (e.g., battery), conductors (e.g., wires), and a load (e.g., light bulb)

• One way: electricity flows from the positive terminal of the power source, through the conductor, and back to the negative terminal

### Types of Circuits
