When calculating the resistance of ammeter and voltmeter, the difference between the measured value and the true value of the measured resistance When measuring resistance by volt ampere method, voltage and current are calculated as resistance. Is the measured resistance larger or smaller, or unchanged?

Small
If the current is normal, the ammeter always divides part of the voltage
If the voltage is normal, the voltmeter always divides part of the current
