From figure below, the data are: $R_{\text{l}\text{o}\text{a}\text{d}}=10,$ man resistance plus ground $=2000.$ If completely failure occurs and a person touch the device. Calculate:

i$)$ Fuse rating design $($based on standard$)$

ii$)$ Current following in this person

iii$)$ Prospective touch volt

iv$)$ Analyze the results obtained
