## Study Notes

### Circuit Types

• Series Circuit: Only one path for current flow, all components share the same current.
• Parallel Circuit: Multiple paths for current, allowing it to flow in different directions.

### Electrical Current and Charge

• Electric Current: Measured as the rate of electrical charge passing through a point in a circuit.
• Coulomb: Charge carried by approximately 6 x 10^18 electrons.

### Resistance and Relationships

• Resistance Concept: Greater resistance leads to less current flow.
• Total Resistance in Series: Calculated as RT = R1 + R2 + R3...
• Total Resistance in Parallel: Determined using the formula 1/RT = 1/R1 + 1/R2 + 1/R3...

### Measurement Devices

• Ammeter: Device for measuring current, placed in series within a circuit.
• Voltmeter: Device for measuring voltage, connected in parallel with the circuit components.
• Ohmetre: Instrument used to measure resistance.

### Ohm's Law and Its Application

• Ohm’s Law Equation: V (voltage) = I (current) x R (resistance).
• Resistance Units: Measured in ohms; a higher value indicates greater difficulty for electrons to flow.

### Components and Circuits

• Components: All items in a circuit, such as resistors, batteries, and capacitors.
• Conductors: Wires or materials that connect components allowing electric current to flow.

### Electric Principles

• Voltage: Energy supplied to the circuit by a power source, measured in volts.
• Current in Parallel Circuits: Divided among components, but voltage remains constant across each component.
• Short Circuits: When electricity flows rapidly through wires, potentially causing damage.

### Characteristics of Electricity

• Electricity: The movement of electrons through conducting wires, representing a form of energy that can convert into heat, light, or sound.
• Static Electricity: Accumulation of charge that does not flow, e.g., rubbing a balloon.

• Polarised Components: Can only be installed in one direction; reversing connections can lead to failure.
• Faults in Simple Circuits: Common issues include miswired components (e.g., LED), breaks in the circuit, flat batteries, and loose connections.
• Electrons and Resistance: Electrons move preferentially through paths of least resistance in a circuit.
