恩,我们这边用示波器,将一欧电阻接在电源两端,用示波器测试两端电压,示波器可以持续监视电压波动,可以很准确的测量出一秒末的电压 " the total battery voltage does not exceed 2,5 V, measured 1 s after a 1 resistor has ) W. T l! ^! z$ t/ w
been connected between the supply terminals of the toy, with any current limiting device ; A; ~. ^# {, L: n- M: e* y, i
short-circuited and without the toy being operated."
- ^$ T' j- h$ O/ }' A/ g! A9 e"the total battery voltage "是一秒末的电压吗?
