1. The ampere is a measure of the amount of electric charge in motion per unit time ―

2. The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance. ... A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when

3. Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.
