DC Circuits Fundamentals - Festo

Which of the following is the definition of current?

• Property of a material to exert a force attraction (or repulsion) on another material from a distance

•  The opposition of a material to the force of electrons

• Rate at which work is produced

• Number of electrons passing through a conductor as a function of time

• Force that causes the flow of electrons in a circuit

Which device is used to measure current?

• Ammeter

• Ohmmeter

• Voltmeter

• Capacitance meter

To measure current the measuring device is:

• Ohmmeter, connected in series

• Ohmmeter, connected in parallel
