  • Electrical Safety in the O.R. - Stanford University

    Web viewCurrent density is the amount of current flowing per unit area. There are situations in which a fairly small current can cause burns or arrhythmias because the current density is large (e.g. the current is delivered to a small area of tissue). The electric companies in the United States have standardized their delivered voltage to about 120 volts.

  • Difference Between Current Transformer and Voltage

    Mar 30, 2020The current transformer has two types, i.e., closed core and wound core. On the other hand, the voltage transformer also has two types, i.e., electromagnetic type and capacitor voltage type. In a current transformer, flux density and excitation current vary over a wide range while it varies within a narrow range in voltage transformer.
