1. The problem statement, all variables and given/known data Our setup: Connect the transformer to an LRC-series circuit(L= 2mH with iron core,C=1mF and R=10Ω). Use the 2V and 6V outputs of the transformer, the effective voltage supplied by the transformer will then be 2 V. Use the digital multimeter to measure the effective voltages(Vob) across the LRC-series, and the voltage across each component. Compare Vr+Vc+Vl with Vob. Qualitatively explain the difference. Well our measured Vob was close to 2V ofcourse:2,07V Vr=1,85V Vc=0,68V Vl=0,72V So the sum of al the voltages across the components is 3.25V. So a difference of 1,18V So my question is how to qualitatively explain the difference 2. Relevant equations 3. The attempt at a solution i though the causes are Dielectic losses and losses by hysteresis, but i am not sure about that and i can't argue why these losses will increase the voltage of the components.
