Resistors can also be used in Alternating Current supplies where the voltages, currents and power being consumed is given in rms values. In the previous tutorials we have looked at resistors, their connections and used Ohm’s Law to calculate the voltage, current and power associated with them. In all cases both the voltage and current…

Electrical Power is absorbed by a resistance as it is the product of voltage and current with some resistances converting this power into heat. When an electrical current passes through a resistor due to the presence of a voltage across it, electrical energy is lost by the resistor in the form of heat and the…

The voltage difference between any two points in a circuit is known as Potential Difference and it is this potential difference which makes current flow. Unlike current which flows around a closed electrical circuit in the form of electrical charge, potential difference does not move or flow it is applied. The unit of potential difference…

Resistors can be connected together in an unlimited number of series and parallel combinations to form complex resistive circuits. In the previous tutorials we have learnt how to connect individual resistors together to form either a Series Resistor Network or a Parallel Resistor Network and we used Ohms Law to find the various currents and voltages across each resistor…

Resistors are said to be connected together in parallel when both of their terminals are respectively connected to each terminal of the other resistor or resistors. Unlike the previous series resistor circuit, in a parallel resistor network the circuit current can take more than one path as there are multiple paths for the current. Then…

Resistors are said to be connected in series when they are daisy chained together in a single line resulting in a common current flowing through them. Individual resistors can be connected together in either a series connection, a parallel connection or combinations of both series and parallel, to produce more complex resistor networks. For resistors…

Resistor Colour Coding uses coloured bands to easily identify a resistors resistive value and its percentage tolerance As there are many different types of Resistor available we need to form of resistor colour code system to be able to identify them. Resistors can be used in both electrical and electronic circuits to control the flow of current…

Resistors are the most fundamental and commonly used of all the electronic components, to the point where they are almost taken for granted but they play a vital role within a circuit. There are many different Types of Resistor available for the electronics constructor to choose from, from very small surface mount chip resistors up to large…
