Academic text (1999) -
Strain gauges respond to the deformation of the metal to which they are bonded by a change in their electrical resistance.
Academic text (1993) -
A change in temperature causes a change in the sensing element's electrical resistance, which is transmitted to a voltmeter for measuring and then to a computer for converting into thermal values.

Morphology
This noun phrase is a direct composition: 'electrical' specifies the domain (electricity) and 'resistance' denotes opposition to flow, so the combined meaning 'opposition to electric current' is literally derivable from its parts. Although somewhat technical, the construction is transparent and follows standard adjective + noun composition found across languages, so a B1 learner who knows both words should understand it.
Etymology
Electrical resistance comes from a simple image: imagine electricity as water in a pipe, and a narrow or rough pipe 'resists' the water so less can pass. So, electrical resistance, literally electrical + resistance, means a material 'resists' or 'slows' the electric 'flow', which is why copper has low resistance and lets electricity pass easily.
