There are many ways tomeasure resistance: ohmmeter, volt-ampere, volt-volt, ampere-ampere, bridge, substitution, comparison, half-deviation and so on. No matter what the method is, the experimental principle is no more than partial circuit Ohm's law and closed circuit Ohm's law as well as...
Calculate the total resistance of the parallel circuit by using the equation 1/Rtotal = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn. This equation states that by adding the inverses of all of the individual resistors, you will get the inverse of the total resistance. Pretend that you have t...
A Parallel Circuit is different from a series circuit in the way that if a component such as a light bulb, LED, or resistor fails the circuit is still active. The electricity flows around the break in the circuit and branches to the parallels. Another characteristic of a parallel circuit is...
Parallel Circuits and the Application of Ohm’s Law Review of Power for Series and Parallel Circuits: Electrical power is the measure of work Power is represented by the symbol “P” The unit of power is the Watt (W) Power is additive in any configuration of a resistive circuit—series, ...
In this post we systematically discuss how to connect diodes in parallel for getting upgrading the overall current specifications of the assembly. This

increases the resistance for the entire circuit. In a parallel circuit, adding a resistor provides another independent path for current to flow. As a result, more current flows for the same resistance. Because of this, when using Ohm’s law to calculate, you will see that resistance is...
If the current increases above the acceptable level, the heat caused by the resistance burns the fuse, thereby cutting off the circuit. If the MOV doesn't stop the power surge, the extra current will burn the fuse, saving the connected machine. This fuse only works once, as it is ...
In the particular “experimental brief” given to some students attending lessons here, internal resistance was to be determined using a “homemade” resistor of approximately ##\;4 \Omega## for the load. Measurements of open circuit voltage, terminal (load) voltage, and current were to be ma...
Resistors can be represented in two different ways, as shown below. You should take care to keep up the consistency in the symbols used. Resistor symbols used in schematic design The unit of the resistance is ohms and is represented by the symbol ‘Ω.’ Sometimes, the symbol ‘Ω’ ca...
