Q3/ A- A voltmeter having a sensitivity of (1500 Ohm/V) reads (75V) on its (150V) scale when connected across an unknown resistor in series with a milliammeter. When the milliammeter reads (10mA), Calculate: 1- Determine the apparent value of the resistance Rx? 2- Determine the actual value of Rx? 3- Determine the percentage error in Rx value?
