The sensitivity of a voltmeter, whose resistance is 150 000 ohms on the 150-volt range, is:

Voltmeter sensitivity is a measure of how much resistance the meter presents to the circuit per volt of its full-scale range. It is calculated by dividing the total internal resistance of the meter by its full-scale voltage. In this case, dividing the total resistance of 150,000 ohms by the voltage range of 150 volts gives exactly 1,000 ohms per volt. This specification helps determine how much the meter will "load" a circuit when measuring voltage. The other options represent basic arithmetic errors, such as dividing the voltage by the resistance or simply misplacing a decimal point.
