Then we will double-click on '''node''' of R2 where '''wire''' needs to be connected.


Similarly we will connect one more '''wire''' between '''Resistor''' R3 and '''capacitor''' C1.


Let us click on one of the '''nodes''' of R3.


Click once to change direction of '''wire.'''


Then we will '''double''' '''click''' on '''node''' of C1 where '''wire''' needs to be connected.
