Ampere or amp (symbol: A) is the unit of electrical current. The Ampere unit is named after Andre-Marie Ampere, from France. One Ampere is defined as the current that flows with electric charge of one Coulomb per second. 1 A = 1 C/s. Ampere meter or ammeter is an electrical instrument that is used to measure electrical current in amperes. When we want to measure the electrical current on the load, the ampere-meter is connected in series to the load. The resistance of the ampere-meter is near zero, so it will not affect the measured circuit.
A Veteran Service Officer (VSO) provides professional assistance to both veterans and their family members by helping them to obtain benefits and services they have earned through military service. VSO's assist veterans and their family members to receive services provided by the Department of Veterans Affairs (VA) and other government agencies.
About the Tutorial. VSAM stands for Virtual Storage Access Method. VSAM is a file storage access method. used in MVS, ZOS and OS/390 operating systems. It was introduced by IBM in 1970's. It. is a high performance access method used to organize data in form of files in Mainframes. VSAM is used by COBOL and CICS in Mainframes to store and retrieve data.
