Practical case: Overvoltage protection
Level: Medium – Disconnect a critical load using a normally closed relay contact when a voltage threshold is exceeded.
Practical case: AND and OR logic using relays
Level: Medium – Build basic logic gates by wiring the contacts of multiple relays in series and parallel.
Practical case: Automatic power switching
Level: Medium – Implement an SPDT relay to automatically alternate between a main power supply and a backup battery.
Practical case: Noise suppression with RF choke
Level: Medium – Demonstrate the high impedance of the inductor at high frequencies to block noise in power lines.
Practical case: Resonance in LC tank circuit
Level: Medium | Analyze the energy exchange and determine the resonant frequency of an AC-driven LC tank.
