    alright so this is a parallel circuit and we al know that the pd is equal everywhere. now i have two question: 1) what if the resistors have different resistances, will the pd across them still be equal, if not what is it gona be? 2) if all the resistors have the same resistance, will al of them...

    dude, R=V/I so when resistance decreases, the pd is bound to decrease. aint it?? :confused:

    I can guide u about nitrogen cycle, but m not so sure about teeth myself. so tag me in any post u find helpful abou teeth. Let's start from th air present in the soil. The plants need nitrate ions. And they get these from the nitrogen present in the air inside the soil. The leguminous (bean)...

    RADIOACTIVITY! In a magnetic field, the beta particles are deflectd more than the alpha particles because they are lighter. But s marking scheme states, the deflection of radioactive particles between two opositly charged plates is due to the the attraction and repulsion from both the plates. So...

    Help, :( How do we determine the exact height of an object after it's light rays pass through a lense. I know when it enlarges and when does it decreases in size, but how do we calculate the exact height? For reference, http://papers.xtremepapers.com/CIE/Cambridge International O Level/Physics...
