Current Electricity

Resistance

The opposition that a material offers to the flow of electric current, measured in ohms (Ω).

Voltage

The electric potential difference between two points in a circuit, measured in volts (V).

Direct Current

Electric current that flows in one direction consistently over time, such as the current from a battery.

Ammeter

An instrument used to measure the current flowing through a circuit.

Short Circuit

An unintended low-resistance path that allows a large current to flow, potentially causing damage or hazards in an electrical circuit.

Resistor

A component in an electric circuit that resists the flow of electric current, generating heat in the process. It is measured in ohms (Ω). (Took me forever to find that symbol)

Circuits

Paths or routes through which electric current can flow, typically consisting of components like resistors, capacitors, inductors, and sources like batteries.

Voltmeter

An instrument used to measure the voltage or potential difference in a circuit.

Switch

A device used to open or close an electric circuit, controlling the flow of current.

Ohm's Law

An important part of physics stating that the current in a circuit is directly proportional to the voltage across the circuit and inversely proportional to the circuit's resistance (I = V/R).

Series

A circuit configuration where components are arranged sequentially along the same path, and the same current flows through each component.

Alternating Current

Electric current that periodically reverses direction, commonly used in household and industrial electricity.

Connecting Wires

Conductive materials used to establish connections between various components in an electric circuit.

A phone charger

Kirchoff’s law

Kirchhoff's Laws explain how electric currents and voltages work in circuits. Kirchhoff's Current Law tates that the total current into a point equals the total current out. Kirchhoff's Voltage Law states that the total voltage around a closed loop in a circuit is zero, indicating energy conservation.

Battery

A device that converts chemical energy into electrical energy and provides a potential difference in a circuit.

Double AA battery in a TV remote

Load

A device or component in a circuit that consumes electrical energy.

A light bulb or an electric motor.

Open Circuit

A circuit in which there is a break, preventing the flow of current.

Parallel

A circuit configuration where components are connected in separate branches, and the potential difference across each component is the same.

Potential Difference (Voltage )

The difference in electric potential energy per unit charge between two points in an electric circuit, measured in volts (V).

Current

The flow of electric charge through a conductor, measured in amperes (A).
