Every 10 years, the U.S. Census Bureau conducts the federal census (U.S. Constitution, Article I, sec. 2). According to the federal 2010 census, Maryland has a population of 5,773,552. As of the 2010 census, Montgomery County was the most populated county in Maryland, with 971,777 residents, followed by Prince George's County (863,420), and Baltimore County (805,029). Kent County was the least populated, with 20,197 residents.
A megohmmeter, or megger as it is more commonly known, is an electrical test instrument designed to test extremely high resistances by producing a DC (direct current) voltage of between 300 and 15,000 volts.
An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements.Megaohmmeters (aka megaohmmeter or in the case of a trademarked device Megger) measure large values of resistance.The unit of measurement for resistance is ohms (Ï).The first ohmmeters were based on a type of meter movement known as a 'ratiometer'. These were similar to the galvanometer type movement encountered in later instruments, but instead of hairsprings to supply a restoring force they used conducting 'ligaments' instead.he unit of measurement for resistance is ohms (Ï).
