circuit branch造句

• Specifically, whereas KVL states that the voltage excitation applied to a loop is equal to the sum of the voltage drops ( resistance times current ) around the loop, the magnetic analogue states that the magnetomotive force ( achieved from ampere-turn excitation ) is equal to the sum of MMF drops ( product of flux and reluctance ) across the rest of the loop . ( If there are multiple loops, the current in each branch can be solved through a matrix equation much as a matrix solution for mesh circuit branch currents is obtained in loop analysis after which the individual branch currents are obtained by adding and / or subtracting the constituent loop currents as indicated by the adopted sign convention and loop orientations . ) Per Amp鑢e's law, the excitation is the product of the current and the number of complete loops made and is measured in ampere-turns.
