A Fresh New Experience in
Project-‐Making and Learning
You might have seen voltage fluctuaAons at your home, which may cause damage to any working electrical appliance. What one needs is a protecAon device or circuit, which can be installed to curb out the voltage spikes and provide a constant voltage output to electrical devices. For this, we can use a zener diode as a voltage regulator.
In this project, you will connect two loads (resistors) in series and connect their
combinaAon to a fluctuaAng voltage source (using a preset) and test the Kirchhoff’s law. However, when you connect a zener diode in parallel to one of the loads, the voltage across the corresponding load becomes constant aPer the reverse breakdown voltage of the zener diode is achieved. All the voltage readings are taken using a mulAmeter and Kirchhoff’s Voltage law is verified in the circuit under different input voltages.
