Question
explain why all measured voltage is not same with estimated voltage in using multimeter as a voltmeter to measure voltage.
Multimeter as Voltmeter Voltages can be categorized as either direct current (DC) or alternating current (AC). In your case, you will only test and measure the voltage of a DC battery using the multimeter as DC voltmeter. When using the multimeter as a voltmeter, always remember that a voltmeter is connected parallel to the device whose terminal voltage is being measured. The positive test probe of the meter (colored red) is connected to the higher potential or positive terminal of the device; the negative test probe (colored black) is connected to the lower potential or negative terminal of the device. Switching the probes (red to '-' and black to '+') may destroy a multimeter.
