what is the formula for determining the time constant in an inductive circuit?
475391
This time constant τ, is measured by τ = L/R, in seconds, where R is the value of the resistor in ohms and L is the value of the inductor in Henries. ... The transient time of any inductive circuit is determined by the relationship between the inductance and the resistance.

Inductors in Series Equation Ltotal = L1 + L2 + L3 + ….. + Ln etc. Then the total inductance of the series chain can be found by simply adding together the individual inductances of the inductors in series just like adding together resistors in series.

Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm's Law, V = IR.

In RC (resistive & capacitive) circuits, time constant is the time in seconds required to charge a capacitor to 63.2% of the applied voltage. This period is referred to as one time constant. After two time constants, the capacitor will be charged to 86.5% of the applied voltage.

At resonance, voltage across the resistor is in phase with the applied current. Voltage across the inductor will lead the applied current by 90 degrees.

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second.

The formula for frequency is: f (frequency) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency).

UJT Relaxation Oscillator consists of a UJT circuit with its emitter connected to a resistor and a capacitor. The timing of the output waveform is determined using the RC time constant. Supply voltage VBB is applied to the circuit. The capacitor starts charging through the resistor R1.

The equation is: charge (coulomb, C) = current (ampere, A) × time (second, s). For example, if a a current of 20 A flows for 40 s, the calculation is 20 × 40.

The ideal diode equation is very useful as a formula for current as a function of voltage. However, at times the inverse relation may be more useful; if the ideal diode equation is inverted and solved for voltage as a function of current, we find: v(i)=ηVTln[(iIS)+1].

When inductors are connected in series, the total inductance is the sum of the individual inductors' inductances. To understand why this is so, consider the following: the definitive measure of inductance is the amount of voltage dropped across an inductor for a given rate of current change through it.

In AC electrical circuits, there are many components where many factors like current, voltage, impedance and frequency are correlated. Talking about inductive load, it's inductive reactance is directly proportional to frequency of operation and thus since current is inversely proportional to the inductive reactance.

The potential difference is V=IR=0.1*5=0.5V, which basically means the statement above is incorrect. I'll assume you know that your supply has an open-circuit voltage of 10 V, but you don't know the internal resistance. If you measure 0.1 A, then you know the total resistance is 100 Ohms.

So as long as the energy is conserved, these are valid. Kirchhoff's law is not applicable for time varying magnetic fields as it is based on the assumption that magnetic field does not fluctuate in a closed loop. Normally, these are applied to lumped circuits. ... In this case, KCL and KVL won't be valid.
