The Multisim oscilloscope shows around 13V peak despite the voltage source being 12V peak. I was expecting 12V. The diode voltage drop is set to 0.1v when forward biased.
Am I missing something?

See the green circles I've added below: -
You are using too big of a maximum time step in your simulation. Try lowering it.

\$\begingroup\$ Good suggestion, but how do I lower the time step? I'm new to this software. \$\endgroup\$– tnstseCommented Apr 24, 2020 at 15:23

1\$\begingroup\$ Search the user's guide for time step, timestep, or TMAX. TMAX will find it quickly in: ni.com/pdf/manuals/371590b.pdf \$\endgroup\$ Commented Apr 24, 2020 at 16:43

\$\begingroup\$ The solution is lurking around the time step, I lowered it and I somehow managed to get the expected reading but lowering time step welcomed me with another problem. Oscilloscope displayed values only for the first quarter period and it didn't display anything for the remaining time. But thank you guys I managed to complete my work although not smoothly. \$\endgroup\$– tnstseCommented Apr 24, 2020 at 19:11
