Of course this is a bad idea. It will likely look like a flash bulb and may explode the glass. Do not do anything like this.

How can you measure the resistance?
It is done with an instrument called a megohm meter or megger. On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts. Applying the proper voltage is essential to not damaging the device you are testing. Working voltages up to 240 volts should use the 300 range. Working voltages up to 600 volts use the 750 volt range and working voltages above 600 use the 1000 volt range. As you can see if you used the 1000 volt range on a device that had a working voltage of say 24 volts you could damage the insulation just by testing it. So meggering a device is non destructive if you use the tester as its instructions tell you to.
What is a megger test?
If you are referring to a megohm meter, it is a test of the insulation properties of such things as electric wiring, motor windings and high power antenna mounts. We use a "megger" or "meg out" electrical wiring and equipment to see if it is shorted to ground in any way.The megger uses much higher voltages to check resistance than a normal Volt-ohm meter.Ideally, you want infinity resistance but I've installed 460 volt motors with 750 meg ohms resistance to ground and had no problem.On the whole megger testing is non destructive.

How do you megger the windings of a single phase motor?
Using a megger you check from either positive or nuetral to ground. The megger should read open (usually OL). It doesnt matter which connection you choose as long as one is ground. If the megger shows anything other than open the windings are bad.
Can you use 300v cable for 240v?
You most certianly can. Voltage ratings on wires are 300V,600V and 1000V. These are the maximum voltages. 120 - 240 on 300V, 480 - 575 on 600V, 1000V wire is a special order used for specialized equipment.
Is a cat5e cable rated at 300V?
yes
Why insulation resistance test is required?
every insulator has its own voltage range depending on its intended use. we test insulation for the required operating voltage range. usa uses a document known as nfpa 7 or nec most common residential wiring 120v to ground is in the 300V class the specified test voltage for 300V wire and wiring devices is 2 times the working voltage +1000v which is 120v x 2 + 1000v = 1240V spec 1600V for industrial wiring its 600V class wire and wiring devices 480V x 2 +1000v = 1960V spec 2200V for most uses a 2500 volt megger is sufficient
Why is there 300 volts ac between the neutral and the earth in a house?
for USA, Canada and other countries running a 60 Hz supply service.In a typical house wired for 120V and 240V, the neutral and earth should be bonded at the main panel, upstream of the circuit breakers, so there should be no difference (though you may notice a small difference as you get further away - such as in an attic). Perhaps you're measuring peak instead of RMS, and you're measuring hot to hot on two different legs of 120V? This would give you 240V RMS, or ~300V peak.So, if you're measuring ~300V peak to peak, maybe what you think is a neutral wire is actually another hot wire from the other 120V leg - or you could be measuring between the two hots on a 240V circuit.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you use 10ga wire for 220 volts?
There is a big misconception that there are two types of wire for different voltages. It is the insulation factor that governs amount of voltage that can be applied to a conductor. Most conductors have three standard voltage insulations, 300V,600V and 1000V. These are the maximum amount of voltages applied to each insulation. The type of insulation and size of a conductor governs the amount of amperage that can be legally applied to the conductor. To answer your question "yes" you can use 120V and 240V on 300V insulation. The "gauge" of the wire is the wire size measured in AWG. )American Wire Gauge. The code book lays out the amount of amps that are allowed on each size.
Why transistor low power device?
Transistors are made up of semiconductor materials with very low power dissipation. Semi conductors are sensitive to high voltages and current and can be easily destroyed. These devices are commonly used for switching as well as amplifying action. Recent developments in semiconductor technology have enabled them to be made to withstand higher currents and voltages. Switch mode power supplies use transistors which work at 300v and many amps.

Why there is two voltage rating on the same cable like 300V or 500V?
The first figure indicates the phase to neutral or ground voltage and the second is the phase to phase voltage. i.e. Vph-ph = 1.732Vph-n
What is the output voltage of an insulation tester which is required to test a 230v circuit?
On a hand crank megger which is used to test insulation breakdown, use the 300V setting. If the megger does not have that setting use 500V as opposed to 1000V for the test. The output of the megger is a DC voltage.
