An apparatus for generating a voltage/current is provided to enhance test convenience by testing simply calibration and normal operation of a clamp type ampere meter. An apparatus for generating a voltage/current includes a sine wave oscillation unit(30) and a precious amplification unit(40). The sine wave oscillation unit electrically oscillates corresponding source voltage and current using a source voltage from a power supplying unit, and generates a constant sine wave according to the oscillation. The precious amplification unit preciously amplifies the voltage and current from the sine wave oscillation unit. The apparatus for generating a voltage/current further includes a voltage/current selection unit(20) and a transformer(80). The voltage/current selection unit selects one of the voltage and current in input stage of the sine wave oscillation unit. The transformer, which is formed between the precious amplification unit and voltage and current output terminals(90,91), delivers voltages from one side to the other side by induction. |
