... Devices for which current through them is directly proportional to the potential difference across device are said to be ‘ohmic devices’ or ‘ohmic conductors’ or simply resistors. In other words the resistance stays constant as the voltage changes. There are very few devices that are trully ohmic. H ...

... The current flows because of the electrical potential (V), sometimes referred to as the voltage applied to a circuit. In much the same way that a gravitational potential will cause mass to move, electrical potential will cause electrons to move. If you lift a book and release it from a height (high ...

Part 2: Using the multimeter as a voltmeter or ammeter
... A voltmeter is a device for measuring voltage. It measures the voltage drop from the red to the black probes. The voltmeter is placed in parallel with the circuit element whose voltage is to be measured. Recall that two elements are in parallel when they share the same pair of nodes and hence share ...

... Resistors are used in electronic circuits to control the potential difference passing through them. If a resistor is too high then an electrical component will not work; if it is too low then the increased potential difference through the component may cause serious damage, for example, bulbs blow a ...
