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 <font style="FONT-FAMILY: ; COLOR: #ff0000">hotter</font> a piece of wire gets, the <font style="FONT-FAMILY: ; COLOR: #ff0000">higher its resitance</font> becomes. On the other hand the <b>temperature</b> of a conducting wire or device changes its<b> R</b>.Tue, 10 Apr 2012 03:17:56 +0100Basics First

<P>There are 3 quantities that every beginners will face when starting to learn about electronics. They are <STRONG>potential difference, resistance and current</STRONG>. 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.</P>
<P>The relation between these three items are expressed as <STRONG>V= R * I</STRONG></P>
<P>Or Voltage equals Resistance times Current. </P>
<P>For example if you pull out one of your electric stove element and measure its resistance to be say 48 Ohms, you can calculate that when full 240 Vac applied to it will cause a current of 5 Amps to be drawn:</P>
<P>240=48 * 5</P>

<P>This blog site is created in the hope to share information about the electronics. Peoples who like to pursue careers in this field or hobbiest are welcome to participate in the upcoming posts.<BR><BR>I am an Electronic Technician who have spent lots of time in this line of work. I found it an exciting and challenging field with lots of rewards.<BR><BR></P>Tue, 05 Jul 2011 03:41:19 +0100
