Frequency is the number of cycles per unit time. It is denoted by "f" and measured in Hertz. The reciprocal of frequency is Time Period, which is denoted by "T".<br />
<br />
f=n/T<br />
for example<br />
<br />
Q: If there are 20 cycles of a wave within 4 seconds then what is the frequency?<br />
Sol: Here, n= 20 and T =4 so<br />
<br />
f=20/4<br />
f=5Hz.</div>Ravi Prakash,B.E(E.TC)Cisco and Microsoft Certifiedhttp://www.blogger.com/profile/08813501038056890198noreply@blogger.com0tag:blogger.com,1999:blog-7948193875571464002.post-87167440633807023372011-10-14T12:13:00.000-07:002011-10-14T12:13:05.902-07:00Basic Electrical Concepts: Current, voltage, resistance, power and Ohm's Law<div dir="ltr" style="text-align: left;" trbidi="on">This is about the electrical concept which is used while learning Hardware.<br />
<br />
<i><b>Current</b></i>: It is the flow of electrons. It is measured in Ampere. It is denoted by I.<br />
<br />
<i><b>Resistance</b></i>: It is the ability to oppose the flow of current. It is measured in Ohms. It is denoted by R.<br />
<br />
<b><i>Voltage</i></b>: It is the potential difference between two points. It is measured in Volt. It is denoted by V.<br />
<br />
<i><b>Powe</b></i>r: It is the product of Voltage and current. It is measured in Watt. It is denoted by P.<br />
<br />
<b><i>Ohms' Law</i></b>: V= I X R, Where r is constant.</div>Ravi Prakash,B.E(E.TC)Cisco and Microsoft Certifiedhttp://www.blogger.com/profile/08813501038056890198noreply@blogger.com0tag:blogger.com,1999:blog-7948193875571464002.post-11706669246944730882011-10-14T12:06:00.000-07:002011-10-14T12:06:27.253-07:00Introduction to PC<div dir="ltr" style="text-align: left;" trbidi="on">Welcome folks,<br />
