Current Measurement Device

A current measurement apparatus configured to quickly block current. The current measurement apparatus includes a first terminal, a second terminal, a resistor interposed in a separated space between the first terminal and the second terminal; a circuit board, a control unit mounted on the circuit board and configured to measure a current flowing in the resistor by using a voltage value between the first terminal and the second terminal and a resistance value of the resistor, and a cutting unit located above or below the resistor and configured to cut the resistor according to a control signal of the control unit.
