graphene super capacitor

is 3.7 V, ibackupmax is 1000na, and the result is 3.7/1e-6 or 3,700,000 Ω. Assume that the capacitor value is 0.2f and is charged to 3.3 V,Ibackupmax is 1000na, and the minimum operating voltage of the oscillator is 1.3 V. The backup time is calculated as follows: -Ln (vbackupmin/vbackupmax) [(vbackupmax/ibackupmax) × C] =-Ln (1.3/3.3) (3,700,000 × 0.2) =689,353 seconds (191.5 hours) Change the capacitance value C to determine the running time of

A simple test method for super capacitance of capacitance topicIf you need to accurately test the parameters of the supercapacitor, need to set up a test platform, to have a data acquisition system, to have data processing capacity, if nothing, but also need to test, in fact, there are methods, but the means are relatively humble, this is the title of "simple" existence of meaning.So, the headline is a little gallimaufry, and the word is actually:The
