What is the name for the flow of electrons in an electric circuit?

• A. Voltage
• B. Current
• C. Power
• D. Resistance

Answer: (B)

The flow of electrons in an electric circuit is referred to as current. Current is defined as the rate at which electric charge flows through a conductor. It is measured in amperes (A), which quantify how many coulombs of charge are passing a specific point in the circuit per second. Understanding current is fundamental for technicians because it directly relates to how circuits operate. It is essential for ensuring that devices receive the correct amount of electrical flow to function properly. The other terms mentioned, such as voltage, power, and resistance, describe different properties of the electrical circuit. Voltage refers to the electrical potential difference that drives the flow of current, power is the rate at which energy is consumed or transferred, and resistance measures how much a material opposes the flow of current. Each plays a role in circuit behavior, but it is current that specifically describes the electron flow itself.
