I’m planning to add a momentary switch to a single loop DC circuit. Will this cause any amount of resistance in the circuit? I’m a complete noobie when it comes to electronics, any resource links or clarification is appreciated. I know the type of material/width of wire and a pot will cause resistance but will any component put in line with the circuit cause resistance, and if so how do I go about measuring the resistance for each component within the circuit?

    If you do want to measure the low resistance, you’ll need dedicated meter with a kelvin connection.

    You can pass a known current through the switch, measure the voltage drop with a multimeter and use ohms law to calculate the resistance.
