The metric system unit for this quantity is "A" (Ampere). 036 * 037 * The ampere, symbol A, is the SI unit of electric current. It is defined by taking the 038 * fixed numerical value of the elementary charge e to be 1.602 176 634 × 10⁻¹⁹ when 039 * expressed in the unit C, which is equal to A s, where the second is defined in terms 040 * of ∆νCs. 041 * 042 * This definition implies the exact relation e = 1.602 176 634 × 10⁻¹⁹ A s. Inverting this 043 * relation gives an exact expression for the unit ampere in terms of the defining constants e 044 * and ∆νCs: 045 * 046 * 1 A = (e / 1.602 176 634 × 10⁻¹⁹) s⁻¹ 047 * <br> 048 * <dl> 049 * <dt><span class="strong">API Note:</span></dt><dd>SI Base Unit</dd> 050 * </dl> 051 * 052 * @author <a href="mailto:jean-marie@dautelle.com">Jean-Marie Dautelle</a> 053 * @author <a href="mailto:werner@uom.technology">Werner Keil</a> 054 * @author <a href="mailto:thodoris.bais@gmail.com">Thodoris Bais</a> 055 * @version 2.1 056 * @since 1.0 057 * @see <a href="https://en.wikipedia.org/wiki/Electric_current">Wikipedia: Electric Current</a> 058 * @see ElectricCharge 059 * @see Time 060 */ 061public interface ElectricCurrent extends Quantity<ElectricCurrent> { 062}
