Hi Parents, we are starting a batch for 2017-19 for IIT JEE Main & Advance plus NEET. IIT Foundation is a course to be undertaken from 9th On wards, do not waste your money from VII/VIII...
Ohm's law: "The potential difference (voltage) across an ideal conductor is directly proportional to the current through it." The constant of proportionality is called resistance'R'. Ohm's law is given...
Do you know that whenever energy is added to the system, the system gains mass? Is there any example of conversion of energy to mass and vice - versa? Yes. A spring's mass increases whenever it is put...
current or voltage we measure for AC are alaways rms(root mean square) value not the actual magnitude so 220 volt ac(rms)= 220*sqrt(2)=311 volt but 220 volt DC alaways gives the magnitude...
