Electrical engineers work on small circuits and large-scale power grids. They work on engineering projects every day.
Basic Electrical Quantities
To understand systems you must learn the basic electrical quantities. These are the concepts of electrical engineering.
1. VoltageVoltage is the difference in potential between two points. It makes current flow through a circuit. The unit of voltage is Volts.
2. Current
Current is the flow of charge in a circuit. The unit of current is Amperes.
3. Resistance
Resistance is the opposition to flow. The unit of resistance is Ohms.
4. Power
Power is the rate at which electrical energy is consumed or produced. The unit of power is Watts.
5. Energy
Energy is the work done by electrical power over time. The unit of energy is Joules or kilowatt-hours.
Ohm’s Law
Ohm’s Law is a principle of electrical engineering. It defines the relationship between voltage, current and resistance. Ohm’s Law helps engineers calculate values in electrical circuits. Ohm’s Law is important for engineering.Types of Circuits
There are different types of electrical circuits.
1. Series Circuit
In a series circuit components are connected in a path. The same current flows through all components. The voltage is divided across components.
2. Parallel Circuit
In a circuit components are connected across multiple paths. The same voltage is across each component. The current divides between branches.
AC vs DC Current
There are two types of current: Direct Current and Alternating Current.Direct Current
Direct Current flows in one direction. It is used in batteries, electronics and solar systems. Direct Current is important for these devices.
Alternating Current
Alternating changes direction periodically. It is used in homes, industries and power grids. Alternating Current is useful for these applications.
Basic Electrical Components
There are basic electrical components.
Resistor
A resistor limits flow and protects components. It is a component.Capacitor
A capacitor stores electrical energy temporarily. It is useful for applications.
Inductor
An inductor stores energy in a field. It is a component.
Diode
A diode allows current to flow in one direction only. It is useful for applications.
Switch
A switch. Closes a circuit. It is a component.
Electrical Safety Basics
Electricity is powerful. Can be dangerous. So it is essential to follow safety tips.Safety tips include:
Always turn off power before working
Use tools
Avoid wet conditions
Follow codes and standards
Ensure proper grounding
