You have to specify they are connected in series or they are connected in parallel and if you know the individual impedances of each coil as you say 3ohm and 5ohm you shall add them and have 8ohm impedance in series connection.

For parallel connection use the formula of parallel resistances.

1/Z = 1/Z(of 1st coil) + 1/Z(of 2nd coil)
