Question

Capacitor = 100 nF , Resistor = 47 kΩ ,Supply voltage = 5 V


●
Calculate the time constant for the circuit.



​

Answer 1

Capacitor = 100μF

Resistor = 47kΩ

Voltage = 5v

calculate the time constant for the circuit

• SOLUTION

T = R * C

where R = the value of the resistors in ohms

C = the value of the capacitor in Farads

T = time constant for circuit in seconds

R = 47Ω = 0.047Ω

1000

So :

T = RC

T = 0.047Ω x 100μF

T = 4.7sec
