A timing device on a pacemaker requires a time constant of 0.5 seconds. What value must the capacitor be if the resistor of the RC circuit has a values of 10,000 Ohms (Ω)?

Respuesta :

Answer:[tex]C=50 \mu F[/tex]

Explanation:

R-C circuit is a circuit with a resistor and a capacitor. It is frequently used in Electronic devices

time constant [tex]\tau [/tex]in R-C circuit is given by

[tex]\tau =RC[/tex]

where [tex]R=resistance[/tex]

[tex]C=capacitance[/tex]

here [tex]\tau =0.5 s[/tex]

[tex]R=10,000 \Omega [/tex]

[tex]0.5=10,000\times C[/tex]

[tex]C=5\times 10^{-5}[/tex]

[tex]C=50 \mu F[/tex]
