Electronic components — resistors, capacitors, transistors
T-Level: Engineering and Manufacturing: Electronic components — resistors, capacitors, transistors
What you'll learn
- 1
Imagine a resistor is like a narrow pipe in a water system — it slows down the flow of water (electricity).
- 2
What does a resistor do in a circuit?
- 3
Drag the slider to see how a 100Ω resistor limits current compared to a 10Ω one.
- 4
A capacitor is like a tiny rechargeable battery — it stores electric charge and releases it when needed.
- 5
Let's trace how a capacitor charges in a simple circuit with a resistor.
- 6
What does a capacitor do?
- 7
A transistor is like a tiny electronic switch or amplifier — a small current can turn a big current on/off or make it bigger.
- 8
Which leg of a transistor is the control (like a tap handle)?
