## Welcome to Electrical Engineering Stack Exchange

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about electronics design.

We're a little bit different from other sites. Here's how:

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

# How can DC charge a capacitor?

I read that a capacitor shows infinite resistance towards DC. While solving questions we use DC to charge the capacitor and use a constant potential difference and current. This contradicts that DC cannot charge a capacitor. Is there any clear idea on how DC cannot charge a capacitor?

But DC current can charge a capacitor.

Just like a water hose with steady flow of water can fill up a bucket.

AC is just a water hose that both fills the bucket (charges the cap) and then sucks the bucket empty (discharges the cap).

An ideal capacitor appears initially to have zero resistance. It's like filling a bucket with water. By the time it's full no more can be added. AC means the bucket is being emptied and filled repeatedly

## Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

• a specific electronics design problem
• the theory and simulation of electromagnetic forces
• a communication scheme
• the writing of firmware for bare-metal or RTOS applications

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

• Consumer electronics such as media players, cell phones or smart phones, except when designing these products or modifying their electronics for other uses
• Programming software for a PC
• Anything else not directly related to electronics design
• Questions that are primarily opinion-based
• Questions with too many possible answers or that would require an extremely long answer
• Questions on the repair of electronics without an in-depth understanding and existing engineer-level troubleshooting steps

## Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.
