How Electronics Work

Heat and Resistivity

March 17, 2012
In the previous blog we mentioned about the relationship between voltage, current and resistance. I should note that eventhough the resistance of a material can be calculated through the other two quantities, there is also another factor that effects it. The hotter a piece of wire gets, the higher its resitance becomes. On the other hand the temperature of a conducting wire or device changes its R.

Basics First

There are 3 quantities that every beginners will face when starting to learn about electronics. They are potential difference, resistance and current. The first one is refered to voltage and the unit of measurement is volts. Unit of resistance is ohms. The current is measured and displayed by amps.

The relation between these three items are expressed as V= R * I

Or Voltage equals Resistance times Current. 

For example if you pull out one of your electric stove element and measure its resi...
