The units for the time constant tau are
WebIn a series RC circuit, the time constant is equal to the total resistance in ohms multiplied by the total capacitance in farads. For a series L/R circuit, it is the total inductance in henrys divided by the total resistance in ohms. In either case, the time constant is expressed in units of seconds and symbolized by the Greek letter “tau ... WebTime constant has units of, Tau – τ When an increasing DC voltage is applied to a discharged Capacitor, the capacitor draws what is called a “charging current” and …

WebSep 12, 2024 · The voltage across the inductor therefore drops to about \(37\%\) of its initial value after one time constant. The shorter the time constant \(\tau_L\), the more rapidly the voltage decreases. After enough time has elapsed so that the current has essentially reached its final value, the positions of the switches in Figure \(\PageIndex{1a ... WebMay 22, 2024 · Consequently, RC is referred to as the charge time constant and is denoted by \(\tau \) (Greek letter tau). Thus, \[\text{Time constant, } \tau = RC \label{8.10} \] As noted, once the capacitor begins to charge, the current begins to decrease and the capacitor voltage curve begins to fall away from the initial trajectory. The solid red curve ...
