Current will NOT flow through a conductor unless its force is stronger than what?

Current will NOT flow through a conductor unless its force is stronger than what?

• A. Volts
• B. Ohms
• C. Watts
• D. Amperes

Answer: (B)

The correct answer is that current will not flow through a conductor unless its force is stronger than resistance, which is measured in ohms. This concept is a fundamental principle of electricity known as Ohm's Law, which states that the current (measured in amperes) through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. In order for current to flow, the voltage (the force that pushes the current) must overcome the resistance. If the voltage is lower than the resistance, the current will not flow. Thus, understanding the relationship between voltage, resistance, and current is key in electronics, particularly in fields such as esthetics where electrical devices may be used. The other measurements mentioned—volts, watts, and amperes—while related, do not directly represent the opposition to current flow that resistance (in ohms) does. Therefore, it's critical to recognize that without sufficient voltage to overcome resistance, current flow will be inhibited.
