Time constant = capacitance x resistance --> farads x ohms simplifies to units of seconds.

(2 x 10-6 farads) x (2 x 103 ohms) = 4 x 10-3 seconds

What is a geometric sequence?

In simpler terms, a geometric sequence is a sequence in which some constant (same) number multiplies every-time to give u the next number in the sequence. 2, 4, 6, 8, 10, 12 - The constant is 2 (E.g. 2 x 2 = 4) 6, 36, 216, 1296, 7776 - The constant is 6 (E.g. 6 x 6 = 36) ------------------------------------------------------------------------------------------------------------------ To figure out the constant number we just divide one number in the sequence by the one next to it on the left. E.g. 36/6 = 6 ++++ That first example, starting at 2 with a constant=2, is arithmetical not geometrical because it simply adds 2 each time. If the constant is a multiplier the series is 2, 4, 8, 16, 32, 64, ...


How do you tell the positive from the negative on a led?

Most LEDs have one lead longer than the other, or a flat side on the rim of the base, to indicate polarity. An LED that has neither of these must be marked in some other way. The only way to identify the polarity of an unmarked LED is to test it. A common AA or C battery in series with a small resistor of 50-100 ohms will do the job. The LED lights when the positive end of the battery ... possibly through the resistor ... goes to the positive end of the LED. (There is no harm to the LED when the battery is connected backwards and the LED doesn't light.)

How do you change time constant of capacitor?

In theory ... on paper where you have ideal components ... a capacitor all by itself doesn't have a time constant. It charges instantly. It only charges exponentially according to a time constant when it's in series with a resistor, and the time constant is (RC). Keeping the same capacitor, you change the time constant by changing the value of the resistor.


What is the act of recovering energy from Capacitor?

A: It is called discharging a capacitor. The charge will follow the rules of a time constant set up by the series resistor and the capacitor. 1 time constant 63% of the charge will be reached and continue at that rate.

How long does it take for a battery to charge a capacitor?

Usually a tiny fraction of a second. Actually it will depend on the characteristics of the the capacitor, and of the remaining circuit (mainly, any resistor in series). The "time constant" of a capacitor with a resistor in series to charge from 0 to a fraction of (1 - 1/e), about 68%, of its final value. This time is the product of the resistance and the capacitance. After about 5 time constant, you can consider the capacitor completely loaded for all practical purposes - i.e., it will be at the same voltage as the battery.


What are the difference between rl and RC circuit?

RL circuit consists of a resistor and an inductor connected in series, while an RC circuit consists of a resistor and a capacitor connected in series. In an RL circuit, the time constant is determined by the resistance and inductance, while in an RC circuit, the time constant is determined by the resistance and capacitance. RL circuits respond to changes in current, while RC circuits respond to changes in voltage.
