red dotted wire problem in simulink

hello , please tell me how to make the dotted red wire to solid black wire in simulink while implementing a circuit, is there any procedure to follow

You are probably attempting to connect a Simulink signal to a physical signal, or vice versa. These are signals in two different domains, and cannot be directly connected. See point#1 in Guy's answer here: http://www.mathworks.com/matlabcentral/answers/14998-simulink-signal-and-physical-signal

but i am simply connecting wire between different physical elements such as ac source and resistor but beside being black it become dotted red .

[Kaustubha Govind]

The AC Source blocks are from SimPowerSystems (which use regular Simulink signal connections), whereas the Resistor is from the SimScape library (physical modeling).

how i can connect Ac source with Current measurement ( red dotted line is coming ) and transformer

take series RLC from simpowersys blockset instead of resisistor.circuit will be ok then. we cannot use low power blocks with simpower system blocksets in Simulink ,that's it.
