Over time, corrosion has developed between the wire end and the screw terminal labeled “4” on the upper side of the top terminal block. This corroded connection now has a high resistance instead of a low resistance as it should. As a result, the light bulb does not energize when the switch is turned ON: Taking voltage measurements with a voltmeter, how do you think this corrosion problem will reveal itself with the switch on the ON position? In other words, which voltage measurement in this circuit (i.e. between which pair or pairs of terminal block points) will be unusual as a result of the bad connection at point #4, and approximately how much voltage should that measurement be?With the corroded connection at terminal #4, the following voltage measurements should read abnormally high (almost full battery voltage, whereas tIn this battery-switch-lamp circuit, the metal filament wire inside the lamp has burned up, so that it no longer forms an electrically continuous connection. In other words, the filament has failed “open.” Of course, this means the lamp will not turn on, no matter what is done with the switch. It also means that most of the voltage measurements taken in the circuit will be the same as with a properly operating circuit. There is, however, one voltage measurement which will be different in the circuit with the burned-out filament than in a properly working circuit. Identify what pair or pairs of terminal block points this different voltage will be measured between, what switch state (ON or OFF) it will appear in, and what this different voltage measurement will actually be relative to the battery voltage.With the filament burned open, the only voltage measurement that will change in the circuit is the voltage across the switch when it is in the OFFIn this circuit, where would you expect to measure full battery voltage (between what pairs of test points)?You should expect to measure full battery voltage with one test lead of your voltmeter touching any of the points along the top wire of the circuitIn this circuit, where would you not expect to measure significant voltage (between what pairs of test points)?You should not measure any significant voltage between any of the test points along the upper wire (A to B, A to C, A to D, etc.), nor between anySuppose this battery and light bulb circuit failed to work.
