• A surplus or deficit of electrons

• A surplus or deficit of protons

• Movement of electric charges

Which of the following is NOT a method of charging an object?

• Friction

Electric current is defined as:

• The total amount of charge in a circuit

• The potential difference between two points

• The resistance of a conductor

• The flow of electric charge

Which unit is used to measure electric current?

• Volts

• Ohms

• Amperes

• Coulombs

In a parallel circuit:

• The current is the same through all components

• The voltage is the same across all components

• The total resistance is always higher than in a series circuit

• The power consumption is always lower than in a series circuit

What is the difference between conventional current and real current flow?

• Conventional current flows from positive to negative, real current flows from negative to positive

• Conventional current flows from negative to positive, real current flows from positive to negative

• Conventional current is measured in amperes, real current is measured in volts

• There is no difference between conventional and real current flow
