Then again, the values of V and I are fixed in accordance to the new voltage output by using the formula Vp/Vs=Np/Ns and VpIp=VsIs. in most calculation questions, the R of the cable is given and the values fit nicely to get the total power. However, if i were to change the resistance of the cable what will happen? Since the values of V and I are constant, how will the V=RI values change. This is because the value of the power, voltage and current are fixed to a certain value due to the usage of the coil formula and the conservation of energy formula. So I'm completely clueless about the scenario that i change the values of resistance within the cable.

I'm hoping that you will be able to help me in this. Thanks so much for the help! :)
