Let’s discuss the last scenario as first to be on the safe side as a first priority. In case of reverse connection, the capacitor will not work at all and if the applied voltage is higher than the value of capacitor rating, the larger leakage current will start to flow and heat up the capacitor which lead to damage the dielectric film (the.

In case of reverse voltage (negative source to positive terminal and vice versa) will blast the aluminum electrolytic capacitor due to the hydrogen ion theory. In this wrong wiring connection, there is positive voltage across the electrolytic cathode and the negative voltage appears across the oxide layer.
Damage to the capacitor Breakdown of dielectric material: When connected with reverse polarity, the dielectric material in polarized capacitors like electrolytic or tantalum can break down, leading to failure. Capacitor leakage: Incorrect polarity can cause electrolyte leakage, reducing the capacitor's lifespan and efficiency.
You could just take note of the fact that electrolytic caps should not be hooked up backwards and move on to the next experiment. In that circuit the current through the capacitor will be limited by the diode and the 100Ω 100 Ω resistor.
A starting point could be in the millisecond range. Voltage scale: Adjust the voltage scale to match the expected voltage across the capacitor. Begin with a range of a few volts/division.
