    alright Usman i got ur question (the soil one).. LDR = light dependent resistance means R is inversely proportional to light asan zaban mai resistance ki resist karnai taqat gir jati hai jaisai hi light around it barjati hai (or gorai is cheez ko sensor kehtai hai bewaqoof banatai hai :P) in...

    no problem well i m seeing this equation first time and apart from transformer this equation is really very usable when transmitting electricity through long wires, when power kept constant volts can be increased to reduce current which causes less loss of energy into heat ( also lower the...

    y power cant be kept constant, what is power ? the source the electrical energy P=IV is mainly applicable in transformers heres ideal transformers complete application (Ns/Np)=(Es/Ep)=(Ip/Is) N is number of coils in either primary or secondry power can be kept constant if and due to it V...

    I is inversely proportional to V if P kept constant ( for P=IV ) first graph is for metallic conductors for what i was talking about , filament one is for thermistors.

    sorry english man, now help me with this according to one equation V is directly proportional to I (V=IR) but according to another equation V is inversely proportional to I (P=IV) how it is possible ??

    look there are two types of resistance 1) Metallic 2)temp dependant resistance for metallic resistors temp is directly proportional to the resistance of a metallic conductor i-e as temp inc R will also increase for temp depen resistance( also called Thermistors ) temp is inversely proportional...
