Which unit is used to measure electric pressure?

The unit used to measure electric pressure is the volt. In electrical terms, "voltage" refers to the potential difference between two points in a circuit. It can be thought of as the force that pushes electric charges through a conductor, much like water pressure pushes water through a pipe.

When a voltage is present, it indicates that there is energy available to move electrons within a circuit, leading to electric current flow. The higher the voltage, the greater the potential for current to flow, making the volt a crucial measure in understanding how electrical systems operate.

Other units listed, such as ampere, watt, and ohm, relate to different aspects of electricity. An ampere measures electric current, a watt measures power (the rate of doing work or consuming energy), and an ohm measures electrical resistance. Each plays an important role in electrical systems but does not quantify electric pressure directly like the volt does.
