In physics, engineering and construction, the direction designated as vertical is usually that along which a plumb-bob hangs. Alternatively, a spirit level that exploits the buoyancy of an air bubble and its tendency to go vertically upwards may be used to test for horizontality. A water level device may also be used to establish horizontality.

They use the following circuitry: The voltage across this capacitor varies directly with the charge. Using Q (charge) = C m (capacitance) x V (voltage), the capacitance is set at the measuring distance of 100 mm. This means that the charge Q varies directly with the voltage V. razor keyboards death speaker5
