Question

(II) Electrocardiographs are often connected as shown in Fig. 19-68. The lead wires to the legs are said to be capacitively coupled. A time constant of 3.0 s is typical and allows rapid changes in potential to be recorded accurately. If $C =$ 3.0 $\mu$F, what value must $R$ have? FIGURE 19–68 Problem 53. (CAN'T COPY THE FIGURE)

Step 1

0 s and the capacitance $C$ is 3.0 $\mu$F. We know that the time constant $\tau$ of a circuit is given by the product of the resistance $R$ and the capacitance $C$, i.e., $\tau = RC$. Show more…
