what is one time constant of a 47 micro farad capacitor in series with a 120 kilo ohm resistor?
Cannot you multiply 47E-6*120E3 ?
To find the time constant of a circuit, you need to multiply the resistance (R) by the capacitance (C).
In this case, the resistance (R) is 120 kilo ohms, which can be converted to 120,000 ohms (1 kilo ohm = 1,000 ohms).
The capacitance (C) is given as 47 microfarads, which can be converted to 47 x 10^-6 farads.
Hence, the time constant (τ) can be calculated as follows:
τ = R x C
= 120,000 Ω x 47 x 10^-6 F
By multiplying these values together, you can determine the time constant of the circuit.
