My answer was: $\displaystyle I_C=(\frac{1}{6}-\frac{1}{2j})(cos(2t)+\sqrt{2}cos(2t-0.25\pi))$ The way I went about doing this was: 1. Ignored V2 and worked out the total impedance in the circuit for V1. 2. Calculated the voltage dropped across the resistor and inductor not in parallel. 3. Subtracted the result in step 2 from V1 to get the voltage across the capacitor as a result of V1. 4. Realising the period and hence the frequency of the function for V2 was the same as for V1, I substituted the value of V2 for the value of V1 in the result in step 3 to get the voltage across the capacitor as a result of V2. 5. Added the results in step 4 and 3 together to get the total voltage across the capacitor. 6. Worked out I = V/Z I could be completely wrong, in which case can someone put me back on the right track. Thanks, Jimmeh Attached Thumbnails
