The full scale value is 20 Volt and it is required to measure a maximum of 1000 Volts with a voltmeter with an internal resistance of 500 kOhm (Ω). What kind of resistance is needed to measure 1000V voltage with this 20V voltmeter, find out by calculating the value of this resistance. Should the resistance be connected in series or parallel to the voltmeter. Briefly explain the reason by drawing a figure.
