Which of the following is true about voltage?
Voltage resists the flow of electrons
The voltage is responsible for moving free electrons through the circuit
Voltage measures the rate at which charge flows through the circuit
The lower the voltage, the brighter the bulbs in a circuit
Electrons flow:
Randomly in all directions
Towards each other
From areas of low potential to areas of high potential
From areas of high potential to areas of low potential
Current can be defined as:
The amount of voltage found in a circuit
The total resistance electrons face within a circuit
The rate at which electrical charge flows through a circuit
The number of electrons a circuit has
Conventional current:
Flows in the same direction as electrons
Flows in the opposite direction as electrons
Sometimes flows with the electrons and sometimes against them
Has no relationship with electrons
