15.(10分)如图所示,电源电动势E=400V,,内阻不计,R1、R2、R4的阻值均为电阻。C为一水平放置的平行板电容器,板间距离d=10cm。。有一带电油滴质量为3.2×电荷量q=+6.410^-10C。,重力加速度取10m/s^2,不计空气阻力。10^-8kg,(1)调节R使带电油滴恰好静止在两平行板之间,求此时变阻器R的阻值大小(结果保留R3R3一位小数);d=10cm(2)若带电油滴从上极板小孔正上方d=10cm处自由下落,为了使油滴不与下极板接触,求变阻器R3的取值范围。

10.如图所示,直线A、B分别为电源a、b的路端电压与电流的关系图线,直线C为电阻R两端电压与电流的关系图线,将电阻R分别接到a、b两电源上,下列说法正确的是A.a电源的电动势大于b电源的电动势B.a电源的内阻小于b电源的内阻C.R接到a电源上时比接到b电源上时消耗的功率大D.R接到b电源上时电源的输出功率比接到a电源上时电源的输出功率大

(3)若电流表A:的量程为I,保持R不变,将R和A看作一个新的电流表,新电流表的A1IR,R1R1A1量程为IB.
