Voltage Divider
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the ...
Voltage Law
The voltage changes around any closed loop must sum to zero. No matter what path you take through an electric circuit, if you return to your starting point you must measure the same voltage, ...
Ohm's law
A picture of a circuit in which you can change the resistance and voltage. You can see the result of your adjustment on a digital voltmeter, and millimeter. Includes a statement and description of ...
Voltage Circuit Simulator
This exercise will help you determine the relationship between voltage (V), amperage (I) and resistance (R). This relationship is called Ohm's Law
Thevenin's Theorem
Any combination of batteries and resistances with two terminals can be replaced by a single voltage source e and a single series resistor r. The value of e is the open circuit voltage at the ...
Faraday's Law
Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil. No matter how the change is produced, the voltage will be generated.
Kelvin's Thunderstorm
This site describes how falling water can be used to generate high voltages
The Hall Effect
Mathematics of Hall voltages and measurement of sheet density and mobility of charge carriers.
Voltage
Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as "electric potential", which then must be distinguished from electric ...
Van De Graaff Generator
Voltages of hundreds of thousands of volts can be generated with a demonstration model Van de Graaff generator. Though startling, discharges from the Van de Graaff do not represent a serious shock ...
