Hello,

Can someone please help me by explaining how to rearrange the following formula to find Vr:-

VL=Vm-Vr/2

I have been trying for hours and I just can not seem to make it work, therefore I would really appreciate any help that you can provide.

Regards,

Sparkyian.:confused:

Thanks mik3, but what I don't understand is how or why you have cancelled out the minus sign in front of Vr. Please Explain?
