Fundamentals of Electricity- Voltage and Current by Mind Map: Fundamentals of Electricity- Voltage and  Current

1. Voltage and Current: What are the differenes

1.1. Volatge is the cause and current is effect

1.2. Electricity

1.3. Voltage

1.3.1. E

1.3.2. V

1.4. Current

1.4.1. I

2. Bohr’s Model of Atom

2.1. Atom

2.1.1. Nucleus Protons (+) Neutrons

2.1.2. Electrons (-)

3. Types of Current

3.1. Direct Current (DC)

3.1.1. Advantages No frequency Easy Transmission of energy Lower line resistance and hence less loss Never induces reactance in the line

3.1.2. Disadvantages Losing energy in transmission Less reliable and available in case of HDVC (high voltage direct current) possible to convert the DC into AC but too complex and expensive

3.2. Alternative Current (AC)

3.2.1. Advantages Easy transform Easy convert to DC

3.2.2. Disadvantages Need Transformers to transform betweens 2 or more different points Risks Dangerous in high volatge Expensive to transmit electric charges for long distances

4. How to use AC or DC

4.1. Use of alternating current and direct current in computers

4.2. Measuring of voltage using voltmeter:

4.3. Measuring of current using ammeter

5. Voltage and Current requirements in a PC

5.1. 230V+3.3A

5.2. 12A if having a lot of drives

5.3. > 1 CPU: 3.3A<I<5A
