Surface Resistivity and Surface Resistance Measurements Using a Concentric Ring Probe Technique L D U electrodes material D (a) Sample #1. L D/2 U electrodes material D/2 (b) Sample #2. Figure 2: Current density. When the voltage U is kept constant, the current density for the thin and the thick bar is the same. The electric current density is often expressed by: J = I
The current interest rate on a 20 year treasury bond is 3.06%. The rate on the savings bond is 0.44% higher than the rate of the 20 Year Treasury bond. Given that US Savings Bonds are just as safe as the 20 year Treasury, getting almost a half-percent more yield is great.
The annual interest rate for EE Bonds issued from November 1, 2016 through April 30, 2017, is 0.10%. EE Bonds issued in May 2005 and after earn interest for up to 30 years. They earn a fixed rate of interest. For the first 20 years, EE bonds earn the same fixed rate that was set when the bond was issued. We may change the rate or the way an EE Bond earns interest for the last 10 years of the bond's 30-year life.
