Understanding Electric Current Concepts

Choose all that is correct about Current?

• The flow of Electrons

• The amount of Electrons per Second

• Exists in an open circuit

• Hard to predict

Are Electrons free to move in a copper wire without any external force?

• YES

• NO

What is the need for a Voltage difference in a circuit?

• To control the flow of electrons

• To slow down the electron flow

• To reduce the amount of electrons

• To force the electrons to follow in one direction

Is there current without potential difference?

• NO

• YES

In which direction actual current flows?

• From top to bottom terminal

• From positive to negative terminal

• From negative to positive terminal

• From bottom to top terminal

What type of current do we get out of the outlet?

• Sawtooth wave

• Alternative Current (AC)

• Direct Current (DC)

• Square wave

Which of those generate DC?

• Batteries

• Wind Turbine

• Solar Panels

• Alternator

How to measure the current in a circuit?

• Connect the Ohm meter in parallel

• Connect the Amp meter in series

• Connect the Amp meter in parallel

• Connect the Volt meter in series

What happens to the current in a series circuit?

• Vanish

• Divides

• Remains the same

• Splits equally

What happens to the current in a parallel circuit?

• Divides

• Remains the same

• Vanish

• Goes to zero
