can it be caused by loose starter bolts or can it be caused by high resistance in the insulated circuit?
or both?

Weak battery, bad starter, or the most common cause, dirty and/or corroded cables. Even if the cables are not corroded or dirty looking the connectors and battery posts build up an oxide coating which causes a high resistance and slow/no cranking. A good scraping or wire brushing of the battery posts and cable connectors is the first thing to try after making sure that no corrosion exists. If the connectors and posts are corroded clean with baking soda and water then scrape or wire brush until shiny.

Loose starter bolts! The fact that you used the term: "high resistance in the insulated circuit", makes this sounds an awful lot like a homework question, meaning you're looking for an textbook answer, right?
It can actually be caused by both and more. Most of the time it'll be do to high resistance or lack of power through out the entire circuit. However, it can also be caused by a mechanical resistance as well, one cause of which could be an improper seat due to loose starter bolts.
And yes, the internals of the starter are a part of the circuit. So worn brushes and cracked coiling will create a high resistance.

Loose Ground Wire, Loose Wires at Starter or Starter Solenoid, Starter Windings Burning out, Weak Battery Loose Connections at Battery, Bad Block to Firewall Ground Strap, Etc.

well it could be 3 things.
1. the bendex can be going out inside the starter which is part of the circuit that helps it to crank, 2 bad batterie,
3. alternator draining the batterie to cause it to crank slowly. well if I were you i would go to your nearest auto store to have your amps and voltage checked to pen point the problem.

If your battery is fully charged, you could need starter bushings and/or brushes. If you are unable to do the job yourself, remove the starter, ask a mechanic friend if you need help. Take it to your favorite auto supply and have it tested. If the solenoid is separate from the starter, remove that also and have it tested. Its best to have it tested before you buy a new one, once you install it, most places won't take it back. You can have the battery tested at the same time.

If it cranks slow it's either a battery that is borderline of failing, corroded battery cable ends, or corroded cables.
