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.
Coupon rate: The coupon rate is the annual interest the bond pays. If a bond with a par value of $1,000 is paying you $80 per year, then the coupon rate would be 8% (80 Ã· 1000 = .08, or 8%). Coupon rate compounding interval: Select the compounding frequency of the coupon rate.
