The energy deposited in a switching element is dominated by the ohmic resistance, the current and the duration of the current pulse. This paper presents measurements of the resistance of a gasdischarge switch and projectile armatures. The measurements have been carried out for different materials as well as for different types of gases for various pressure and current values. As a first result we show that the resistance decreases with increasing current and ranges between 7 and 0.5 m{Omega} for the spark gap (10 {le} 210 kA) and between 20 and 0.25 m{Omega} for the plasma armature (10 {le} 1 {le} 400 kA). A charge of more than 400 C can be transferred by the spark gap.
