WebThe RC time constant, also called tau, the time constant (in seconds) of an RC circuit, is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in … WebIn the first time constant τ, the current rises from zero to 0.632 I0, and 0.632 of the remainder in every subsequent time interval τ. When the inductor is shorted through a resistor, current decreases as I = I0e−t/τ (turning off). Here I0 is the initial current.
WebThis 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. This then forms the basis of an RL … WebNov 5, 2024 · A steady current flows through a circuit with a large inductive time constant. When a switch in the circuit is opened, a large spark occurs across the terminals of the switch. Explain. 19.
