Electric Circuits

Powering the World

Electric circuits are pathways for electric current, allowing energy to flow and power devices. They can be as simple as a flashlight or as complex as a computer.

Basic Components

  • Voltage (\(V\)): The energy per charge, like the push that moves electrons.
  • Current (\(I\)): The flow rate of electric charge.
  • Resistance (\(R\)): How much a component resists the flow.

Ohm's Law

The relationship between voltage, current, and resistance is given by: \[ V = I R \]

Circuit Types

  • Series Circuits: One path for current.
  • Parallel Circuits: Multiple paths for current.

Everyday Use

Circuits are everywhere: phones, cars, and even your home's lights rely on them.

Key Formula

\[V = I R\]

Examples

  • Turning on a light switch completes a circuit, and electricity flows to the bulb.

  • Batteries in a remote control power the buttons through a circuit.

In a Nutshell

Electric circuits let us control and use electricity safely and efficiently.

Key Terms

Current
The flow of electric charge.
Resistance
How much a material slows down electric current.
Voltage
The push that makes current flow.
