Resistance standards and decade boxes provide a highly accurate standard value of resistance for calibration and testing.

Shunts resistors are connected in parallel with an instrument or component to divert electrical current.

DC motors are most commonly used in variable speed and torque applications.

Capacitance standards and decades provide a highly accurate standard value of capacitance for calibration and testing.

Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).

Resistors are electrical components that oppose the flow of either direct or alternating current.

Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions
