The first thing that comes in the study of electrical issues is the current voltage, power and so on. There is a lot of interest in knowing about them all. In this post we will discuss this common topic.
- What is the current and how many types?
- What is the voltage and how is the voltage measured?
- What is Power?
- What is the watt and how to measure watt?
- What is energy?
Today's discussion
1. What is the current and how many types?
The electrons in the conductor are called the current in the direction of the flow. That is, the flow of electrons through conductor or conduction current
Types of cases:
Current can be divided into two parts
1. Alternating Current or AC 2. Direct Current or DC
Alternating Current:Normally the current value of the current change is called an alternating current.
Direct Current:DC or Direct Current whose value does not change over time.
Below are illustrations of Alternating and Direct Current.
