Question

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)?

Answer 1

Answer:$C=50 \mu F$

Explanation:

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

time constant $\tau$in R-C circuit is given by

$\tau =RC$

where $R=resistance$

$C=capacitance$

here $\tau =0.5 s$

$R=10,000 \Omega$

$0.5=10,000\times C$

$C=5\times 10^{-5}$

$C=50 \mu F$
