 1st November 2010, 02:04 AM #11 wdcw   diyAudio Member   Join Date: Jul 2010 No worries, can I still just sum the two currents together seeing that the circuit is Inductive & Capacitive. Cheers

When you sum the inductor current with the capacitor's, remember to use vectors as their phases won't match LTSpice will do this for you though - just mouse over the voltage source and a current symbol will appear - click to graph the overall current from that source. __________________ 'The total potential here must be nothing less than astronomical.'

 1st November 2010, 02:37 AM #13 wdcw   diyAudio Member   Join Date: Jul 2010 abraxalito I need to find the total current through the Capacitor when a 1050Hz signal is injected into a 230V signal. So I am not sure a phasor diagram is going to find that, is it? I have no value for L so I am not sure what IL or XL is. Basically two voltages with different frequencies when mixed, do there currents add together? Cheers

You have the C value, that's 4.9uF. Given that the question isn't asking about current into the inductive part (which means both phases are staying at 90), you can add together the current at 50Hz and that at 1050Hz. I haven't tried two different frequency sources in LTSpice myself, don't know if that works. A phasor diagram when there's only currents in the same phase seems a bit overkill To answer your final question - its 'yes' when the currents are in phase and the load is a linear one (like a capacitor as you've got here). __________________ 'The total potential here must be nothing less than astronomical.'

You're welcome, its blown a cobweb or two out of my rusty brain in the area of phasors... __________________ 'The total potential here must be nothing less than astronomical.' 'Nothing less.
