In electronics, conductance is a measure of the current produced through a circuit element for a given applied voltage. Usually denoted by the letter G, conductance is the reciprocal of resistance, R. The unit of conductance is the siemens (S). The conductance of a conductor depends on many ...
Most electrical calculations involving resistance, voltage, current or power are solved using Ohm's law. Ohm's law, discovered in 1827 by Georg Simon Ohm, states that the current in a conductor is proportional to the voltage and inversely proportional to the resistance. Since power, measured in...

3. Using a Ground Resistance Tester A ground resistance tester is a specialized instrument designed for this purpose. Here’s how to use it:Preparation:Read the tester’s manual to understand its functions.Disconnect the grounding conductor from the system to ensure accurate results.Setup:Connect ...
To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm's Law isE=I⋅R, which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop. ...
How Do You Calculate Amps Without Watts? In the unlikely event that you don’t know the wattage of an appliance, but you do know the voltage (almost always 230V) and the resistance (ohms), you can calculate the amperage of the device. ...
3. Calculate Number of Turns Determine number of primary and secondary turns to achieve turns ratio based on voltages Account for minimum required inductance Estimate effective core area 4. Estimate Conductor Thickness Select copper thickness/weight to handle expected load current Account for allowable ...
recommend) will have no effect on the corrosion resistance of the joint as there will be no space for the solder to enter. Ultimately the crimp process aims to deform the wire and crimp to a preset level, to eliminate the spaces as well as cold work the wire to a pre-determined level...
Knowing basic electronic principles, circuit board components and their behavior is crucial. You must also understand the basic physics and mathematics concepts to calculate parameters like impedance, signal timing, and power distribution. Basic electronic component symbols ...
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...
