小亮同学在测量额定电压为2.5V的小灯泡工作时的电阻实验中:已经连接了如图甲所示的部分电路。

(1)请你用笔画线代替导线将图甲中的电路补充完整。

(2)小亮同学连接完电路后,闭合开关,发现电压表向右偏转,而电流表指针向零刻度的左边偏转,造成这一现象的原因是                 

(3)小亮同学排除故障后连接成了如图所示的电路,闭合开关,发现灯泡较暗,为了让小灯泡正常发光,应将滑动变阻器的滑片向      端(选填“A”或“B”)移动。

(4)当小灯泡正常发光时,电流表指针如图13乙所示,则通过灯泡的电流是

________A,小灯泡正常工作时的电阻是  Ω。(结果保留一位小数)

(5)小亮移动滑片又测量了两次数据后发现,三次测得的灯泡的电阻相差较大,与其他同学交流也是同样的情况,由此总结得出:当灯泡两端的电压增大时,通过灯泡的电流增大,灯泡的亮度变亮,灯泡的电阻

Certificates are (71) documents attesting to the (72) of a public key to an individual or other entity. They allow verification of the claim that a given public key does in fact belong to a given individual. Certificates help prevent someone from using a phony key to (73) someone else. In their simplest form, Certificates contain a public key and a name. As commonly used, a Certificate also contains an (74) date, the name of the CA that issued the Certificate, a serial number, and perhaps other information. Most importantly, it contains the digital (75) of the certificate issuer. The most widely accepted format for certificates is X.509, thus, Certificates can be read or written by any application complying with X.509.
