KVL for AC circuit:
1. channel 1 in A, channel 2 in B, we will minus 1-2 for Vr1;
2. function voltage will applied as correct freq and correct amplitude for vmax vpp; vpp= 2* Vmax;
3. Channel's earthing will be grounded and positive will connected to A node and other is in B node.
4. horizontal in right and vertical in left will display good division of graph;
5. click channel 1 and 2, then select DC to convert it AC;
6. click position to select axis for granted;
7. Click menu on off to not display the items on right.
8. We can change the Vmax and Vpp for c1 and c2 in going to measure, to show correct display.
9. I have to minus c1- c2; we can do this in " math'' section; operation will be selected as '-';
it will create new sine graph of c1-c2;
10. for measuring we need cursor; mode- manual; source- math;
type - voltage;
take cursor B to zero , and take cursor A to the peak of the minus graph;
select a specific cursor and rotate universal knob to selection; we measured vpp/2 by oscilloscope and now we have to measure vrms by multi meter
