Question

tor is charged to an initial voltage of 1OV micro- discharge through a 40 kQ resistor. You take 10 is then tsof voltage versus time and record a vol 10 It is rements o and a voltage reading of.47 volts after 60 after 50 seco What is your percent of .47 volts after 60 seconds. ent error against the theoretical value of the voltage reading after three time constants? 6% -6% c.60% d. -60% What is the equation for the voltage of a charging capacitor in a RO circuit? 12. Which of the following changes will increase the time constant of an RC circuit? @ Increase the resistance from 1 kC2 to 100 kΩ and decrease the b, Decrease the resistance from 10 kΩ to 1 kΩ and increase the c. Increase the resistance from 1 kΩ to 100 kΩ and decrease the d. Decrease the resistance from 100 kΩ to 1 kΩ and decrease the capacitance from 10 micro-Farads to 1 micro-Farad. capacitance from 1 micro-Farad to 10 micro-Faradss capacitance from 100 micro-Farads to 1 micro-Farad. capacitance from 10 micro-Farads to 1 micro-Farad.

Answer 1

Question 10 Answer i don't know

For 11anser is option (d) V = V₀ *(1-e^-t/RC)

For 12 answer is option (a)

From t= R *C
