Testing a capacitor with a multimeter can be quite handy! First, ensure the capacitor is discharged for safety. Then, using a multimeter set to the capacitance mode, connect the probes to the capacitor leads. The multimeter should display the capacitance value, and you can compare it to the specified rating. If it's way off, the capacitor might be faulty. Have you tried this before, or is it your first time working with capacitors? Let me know if you need more guidance!
