Hardware Engineering

Hardware is fundamental to the field of electronic engineering, without it we wouldn't have any digital devices as we know today.

Through taking this course you will be able to intuitively analyze, design and test real world complicated practical circuits such as the one shown below!

6. How to effectively use industry standard circuit simulation tools

7. Techniques to diagnose and repair faulty PCB's

Let's start the journey!

Atoms
To begin our journey into analog electronics we need to understand the basics of atoms. At their core, atoms are the building blocks of matter. The word atom is derived from the greek word meaning indivisible as it was originally thought that atoms were the smallest entities in the universe
Conductors and Insulators
Conductors:A conductor is a material which enables electrons to flow freely between atoms. Most metals are regarded as conductors which have valence electrons in the outer shell that are free which repel each other. Once an electric field is applied to copper the free electrons propagate through the…
Electric Potential and Voltage
We have learnt that charges experience a force when placed in an electric field and we can say that this electric force performs work to move the charge between two points. Electric potential is the work required to move a charge from a reference point to a specified point. Expressed
Electric Current
To put it simply, electric current is the flow of charge. It is defined as the total charge which pass a point in the circuit each second and has the units of Amperes [A] or Coulombs per second [C/s] by definition. Where I is the current in Amperes, Q
Resistivity, Conductivity, Resistance and Conductance
ResistivityResistivity is an attribute of a material, such as copper for example, which is proportional to how strongly it resists an electric current flowing through it. Hence a material with a high resistivity strongly opposes electric current flowing through it and conversely a material with a lo…
Ohm’s Law
Ohm’s Law is a fundamental and basic law of electronics which describes the relationship between voltage, current and resistance. It states that the current flowing through a resistor is proportional to the voltage across it and inversely proportional to the resistance. This makes sense intuitively…
Ideal Voltage Source
An Ideal Voltage Source has several properties which allow the voltage source to always provide the rated voltage independent of the circuit resistance and current drawn. These properties are: Never goes flatAlways maintains the same voltage independent of currentVoltage sources can Supply or Absorb…
Ideal Current Source
An Ideal Current Source has several properties which allow the current source to always deliver the rated current to the circuit independent of the circuit resistance and voltage across its terminals. These properties are: Has the same current flowing through it regardless of the voltage across its…
Series Circuits
Series Circuits are circuits which satisfy the following rules: The same current flows through each element, the current doesn’t branch offThey have one common terminal which is not connected to another current carrying componentThe key concept is that the current is the same through series componen…
Parallel Circuits
Parallel Circuits are circuits which satisfy the following rules: The same voltage exists across each branch, the current branches offTwo elements, paths, branches or networks are in parallel if they have two common terminalsA parallel circuit has two or more branches for current to flow through and…
Grounding and Safety
Ground:When voltage is spoken of it is always with reference to the electric potential at a reference point. In electronics ground (or earth) is a name we give to this reference point, and for a circuit with a battery for example this point is usually taken to be the
Series-Parallel Circuits
Series-Parallel Circuits are circuits which are composed of series and parallel connections. To analyse these we need to identify the series and parallel pieces and apply their rules to them. Below are summaries of the key rules for series and parallel circuits which will help us to identify and sim…
Circuit Terminology
This topic will describe commonly encountered circuit terminology. CircuitA circuit is a group of components connected together in a loop. At a minimum it will feature a voltage or current source and a resistance. Note if a voltage or current source is connected only by wires then a resistance still
Kirchoff’s Voltage Law
Kirchoff’s Voltage Law (KVL) is a circuit law related to voltages in a closed loop. It states that the the sum of voltages traversed in a closed loop is equal to zero. This is also known as the conservation of energy. This is mathematically described as: Expressed another way, the
Kirchoff’s Current Law
Kirchoff’s Current Law (KCL) is a circuit law related to currents entering and exiting a junction. It states that the the total current entering a junction is equal to the total current exiting the junction. This is a consequence of the conservation of charge where charge can neither be created
