Why is it necessary to insert resistance in series with the motor armature when starting a dc motor?
Inserting resistance in series with the motor armature when starting a DC motor is necessary to limit the inrush current. At startup, the motor has low back electromotive force (EMF) due to its initial stationary state, leading to a potentially very high current that could damage the motor windings or the power supply. The resistance helps to gradually increase the current as the motor accelerates, allowing it to reach its operational speed safely. Once the motor is up to speed, the resistance can be removed or reduced to improve efficiency.

Why the air gap between stator and armature of electric motor is kept small?
Obviously, if there wasn't a gap, the rotor would not be able to rotate! However, the gap should be as small as possible in order to minimise the reluctance of the magnetic circuit (reluctance is equivalent to resistance), because the reluctance of air is very much larger than for silicon steel.
How long will it take to fully charge a capacitor in a series RC ciRCuit with a 6microfarad capacitor 2Kilohm resistor and 141 volt supply?
The time it takes to fully charge a capacitor depends on the capacitance and resistance of the circuit; the voltage is irrelevant. The equation you need is:t = 5RCwhere: t = time in seconds, R= resistance in ohms, and C =capacitance in farads.So you should now be able to calculate the time for yourself, but remember to convert the resistance into ohms and the capacitance into farads before you insert the figures into the equation.
How do you load slides in an argus 543 slide projector?
To load slides in an Argus 543 slide projector, first open the slide tray by lifting the latch or pressing the release button. Insert the slides into the tray, ensuring they are oriented correctly with the image side facing up and the notches aligned with the tray. Once all slides are loaded, close the tray securely and adjust the focus and settings as necessary before starting your presentation.
How do you adjust magneto on 6.5 hp Briggs engine?
The armature needs to be slightly loose with the magnets away from it, insert a business card or index card between flywheel and legs of the armature, slowly rotate the flywheel until magnets pull the legs close, tighten armature rotate flywheel until magnets are away, remove card and you are done.
