Circuit Elements Guide

Power Sources

Battery: Provides the energy to make electricity flow. Like the ones in flashlights or toys!

V

Wall Outlet: Electricity from your home's power system. Be careful - real outlets have MUCH more power than batteries!

Basic Components

Resistor: Controls how much electricity flows. Like a narrow part in a water pipe that slows down the flow.

Light Bulb: Uses electricity to make light. The electricity heats up a wire inside until it glows!

Switch: Turns the circuit on or off. Just like a light switch at home!

Buzzer: Makes noise when electricity flows through it. Found in doorbells and alarm clocks!

Tools

Wire: Connects components together. Electricity flows through wires like water through pipes!

Ground: The reference point for voltage. Think of it like sea level for measuring mountains!

Probe: Measures voltage or current at a specific point. Like a thermometer for electricity!

Delete: Removes components from your circuit. Oops! Made a mistake? Just delete it!

Circuit Types

Series Circuit: Components are connected one after another in a single path. If one light bulb burns out, they all go dark!

Parallel Circuit: Components are connected across from each other with multiple paths. If one light burns out, the others stay on!

Formula Guide

  • Ohm's Law: V = I × R (Voltage = Current × Resistance)
  • Electric Power: P = I × V (Power = Current × Voltage)
  • Resistors in Series: Rtotal = R1 + R2 + ...
  • Resistors in Parallel: 1/Rtotal = 1/R1 + 1/R2 + ...
