The Flow of Electric Charge

Electricity is all about charges moving through wires and circuits. Circuits can be as simple as a flashlight or as complex as a computer.

Key Components

• Voltage (V): The push that moves charges.
• Current (I): The flow of charges.
• Resistance (R): What resists the flow.

Ohm’s Law (\( V = IR \)) connects these ideas.

Series vs. Parallel Circuits

• Series: One path for current; all devices share the same current.
• Parallel: Multiple paths; devices share the voltage.

Real-World Uses

Every electronic gadget you use depends on electric circuits!
