Understanding Electric Current: Flow of Charges

Learning objective

Learning Objectives

At the end of the lesson you will understand electric current, its relationship with charges and time, and how to measure it.

What do you already know about electric current?

What is Electric Current?

Electric current is the flow of electric charge. It is measured in amperes (A), indicating how much charge flows through a point in a circuit per second.

Charge, Time and Current

The relationship: Current (I) = Charge (Q) / Time (t). Current is measured in amperes, charge in coulombs, and time in seconds.

Measuring Electric Current

Electric current is measured using an ammeter, which is connected in series with the circuit.

Electrical Symbols Worksheet

Match the names with their electrical symbols: Ammeter, Battery, Resistor, Wire.

Diagram: Measuring Current

Illustrate a circuit with an ammeter measuring current. Show connections in series.

Interactive Activity

Discuss in pairs: How does the flow of current affect a light bulb in a circuit?

Review & Q&A
