for kilo capital K, for mega it is not capital M but capital "MEG", please remember it is MEG for mega. for giga capital G terra capital T.

The various analysis you can do are DC analysis for finding out unknown voltages and currents in DC circuits, AC analysis for finding unknown variables in time varying circuits, transient analysis to find out the nature of voltages and currents at the time of switching, i.e when a switch is turned on or off. This has to be measured at very short intervals of time for example micro or nano time intervals. In DC analysis, though there is no time variable, still to run the simulation we need to mention stop time. you can input this value to be something like 1 second. DC sweep is another important analysis for plotting VI characteristics of BJT or MOSFET, i.e you can change the value of voltage gradually and plot the response i.e. current by simply inputting the start value, end value and interval. you also can do noise analysis and get transfer function of a circuit from DC transfer analysis.

Mesh analysis problem is solved in DC as well as AC circuit
