When you look at a battery pack or a computer, what does the rest of the system need to work with? The display, storage space, and processing power needed to run the software and hardware integrated into a good system.
The same goes for applications and devices. If you want to use your computer to access the Internet, you must have enough storage space to stores your files. If you want to use a smartphone as your personal mobile device, you need enough processing power to make things useful.
Some things work with some others, and if you do not have something that works with something else, then there is something wrong with you. You need to find what evaluates well for you and your needs.
Then, use Ohm’s law to find the voltage drop across the capacitor
Once you know the capacitance of the first capacitor, it is easy to find the voltage across it using Ohm’s law.
Simply connect a known length of wire to the positive terminal of the first capacitor, and connect a known length of wire to the negative terminal. Using your computer or phone’s calculator, multiply the width of the two wires by their thickness, and then add them together.
That voltage difference is what you would find if you connected one end of a second capacitor to that second capacitor’s negative terminal and the other end to that second capacitor’s positive terminal.
By doing this across two capacitors, you can make sure that they are working properly together.
Finally, express your answer in terms of Δv
When you know the voltage across the first capacitor, the next one up in parallel may be difficult. It is more likely to be a variable resistance, or variable voltage, component.
Creating a general principle for what next up in parallel capacitors looks like may help guide you when looking for an upgrade.
Check your answer by calculating Δv using both methods
If you do not find the voltage difference between the first and second capacitor, your answer is correct. You did it!
If you calculate the voltage difference using your soldering skills, you have checked your answer. If you use a logic circuit, you have checked your answer. If you match both answers, you are good to go!
This is a great way to test your soldering skills as there is no risk of damage to any components. You can also check your work before moving on to the next step if you need help doing this.
