The term L/R is called the Time Constant (τ) of theRL series circuit. It is defined as the time taken for the current to reach its maximum steady state value. The term V/R represents the final steady state value of the current in the circuit....
DERIVATION OF THE EXPRESSION OF THE GRAVITATIONAL F Let coil current is I , the gap of the slider M and the electromagnet is e , the expression of the gravitational F is as follows: Relation to the reluctance of the magnetic circuit R dl dl ...
Without compromising the generality and simply for ease of writing and schematic representation, we consider that the circuit elements in each phase are equal; i.e., L1 = L2 = L3 = L and R1 = R2 = R3 = R. Accordingly, the following equation is obtained by summation from the last equa...
