What unit represents electric strength?

  1. Ohm

  2. Volt

  3. Ampere

  4. Watt

The correct answer is: Ampere

The unit that represents electric strength is measured in volts. Electric strength refers to the ability of a material to withstand electric field without breakdown, and in the context of electricity, it typically relates to the potential difference across a unit distance in materials. While the other terms relate to different aspects of electricity, volts specifically measure the electric potential or strength in circuits. Ohm measures electrical resistance, ampere measures the flow of electric charge (current), and watt quantifies electrical power. All of these terms are important in understanding electrical concepts, but volts directly correspond to the concept of electric strength as a measure of potential difference.
