Switching and measuring voltage sources with high internal impedance are subject to a number of errors, including offset currents, stray leakage paths, and electrostatic interference.
切换和测量具有高内阻的电压源会受各种误差的影响，包括偏移电流、寄生漏泄通路，以及静电干扰。
When the electric voltage and current are measured with voltmeter and ammeter, certain measuring errors could occur due to the inherent resistance.
在实际使用电压表、电流表测量电压、电流时，因测量仪表的内阻会产生一定的测量误差。
