Generally, it is recommended to wait for 5 times the time constant of the circuit for capacitors to completely discharge. This means waiting for about 5RC, where R is the resistance in the circuit and C is the capacitance. However, for safety reasons, waiting for a few minutes to ensure complete discharge is a good practice.
To completely block the light, the students should orient the two filters in a way that their polarization axes are perpendicular to each other. This will prevent any light from passing through both filters.
Capacitance is defined as the maximum charge stored in a capacitor per unit potential difference. According to this definition, the formula should be : Capacitance = Charge stored / Potential Difference
It is not safe to boil Christmas lights to clean them. Boiling can damage the wires and create a fire hazard. Instead, unplug the lights and gently wipe them with a damp cloth. If needed, use a mild soap solution. Always ensure the lights are completely dry before plugging them back in.
Isopropyl alcohol and a microfiber cloth are commonly used to clean a CPU and heat sink. Apply the alcohol to the cloth and gently wipe the surfaces to remove any dirt or thermal paste build-up. Ensure both components are completely dry before reinstalling.
To achieve clear ice, water should be boiled for about 5 minutes before freezing it.
No, it is not necessary to fully discharge rechargeable batteries before recharging them. In fact, it is better to recharge them before they are completely drained to prolong their lifespan.
It depends on what type of battery it is. Ni-CD battery do need to be discharged completely before recharging it (I would recommend getting a discharger), Ni-MH batteries can be discharged but don't need to be, and Li-PO batteries should absolutely not be discharged completely, because they catch fire and explode when fully discharged (Ni-CD batteries have a memory effect, while Ni-MH and Li-PO batteries do not).
The primary precaution when working on any capacitor is to ensure that the capacitor is disconnected from electrical sources and that it has been fully discharged.
No, completely discharging a lithium battery will damage it significantly reducing its ability to hold charge. However a lithium battery that is discharged to just a few percent of completely discharged before being recharged will get more successful recharge cycles than one that is recharged much earlier. Its a somewhat tricky balancing act and I have destroyed a few batteries myself by not stopping the discharge soon enough.
Absolutely.
In the case of many electronics, you can discharge any capacitors by first unplugging it (and disconnecting any batteries) and then pressing the power button. The capacitors should drain when the circuit is opened.
At least 60 minutes because they contain capacitors which hold electric current.
The scope is removed. The patient is covered completely. The short-acting sedation wears off. The patient's vitals are often checked. Within the hour, you should be discharged. But you should not drive yourself home.
Its good for it. Any device with a chargible battery is better off letting the battery run all the way down before a recharge due to the fact that battery's in general have a certain ammount of charges they can do before it gets worn out. So yes, it is good to charge a completely dead battery then starting to charge half way.
You should stop your vehicle completely at a stop sign before proceeding.
The vasectomy should make him completely infertile; no pregnancy will result.
No, they should be listed with all debts you want discharged, provided they were made before you filed. If the payday loans were borrowed before you declared bankruptcy and they are discharged make sure you do not pay back a penny on this debt, or you will owe it!! Payday lenders know how to use every trick and how to use the legal system better than you do!
