Electricity Mind Map
Understand electric current, sources, circuits, conductors, insulators, series connections, parallel connections and circuit symbols through one visual lesson.
What Is Current Electricity?
The movement of electric charge through a conducting path.
Main Sources of Electricity
Different devices and systems provide electrical energy.
Cell & Battery
Chemical energy is converted into electrical energy.
Mains Supply
Electricity supplied to homes, schools and workplaces.
Generator
Mechanical energy is converted into electrical energy.
Solar Cell
Light energy from the Sun is converted into electricity.
Electric Cell
A cell has two terminals: positive and negative.
Dry Cell
A compact source of electricity used in torches, clocks and toys.
Flow of Electric Charge
A complete path allows charge to move continuously.
Conductors and Insulators
Materials behave differently when placed in an electric circuit.
Allow Current to Flow
Conductors contain charge carriers that can move easily through the material.
- Metals such as copper and aluminium
- The human body
- Impure water
Resist the Flow of Current
Insulators do not allow electric charge to move through them easily.
- Rubber
- Dry wood
- Plastic and ebonite
Electric Circuit
A circuit is a path through which electric current can flow.
Closed Circuit
The path is complete, so current flows and the connected device can work.
Open Circuit
The path has a break, so current stops and the connected device does not work.
Series and Parallel Connections
Components can be connected in one path or in separate branches.
Series Connection
Components are connected one after another in a single path. If the path breaks at one point, current stops throughout the circuit.
Parallel Connection
Components are connected in separate branches. One branch can continue working even if another branch is open.
Common Circuit Symbols
Standard symbols make circuit diagrams clear and universal.

Frequently Asked Questions
Tap any question to reveal its answer.
Current electricity is the continuous flow of electric charge through a conductor. Electric current is measured in amperes.
Common sources include electric cells and batteries, mains electricity, generators and solar cells.
A conductor allows electric current to pass through it easily, while an insulator strongly resists the movement of electric charge.
An open circuit has a break in its conducting path, so electric current cannot flow through the complete circuit.
A series circuit has one current path, whereas a parallel circuit has two or more branches. Components in parallel can operate independently.
