Question

(A) Figure P14.15a represents a simple voltage divider circuit. A voltmeter with an internal resistance of 1 M disconnected to measure VA, the voltage across R2. Calculate the voltage measured for Va and the error from the actual value. If the same voltage divider is constructed using 200kN resistors, as shown in Figure P14.15(b), calculate the measured VA and the error from the actual value.
