Problem

A control circuit contains a

47\,k\Omega

resistor in series with a capacitor. The circuit must reach at least

80\%

of its final charge within

10\,\text{ms}

. Which capacitor is the smallest value that satisfies the specification? a)

0.10\,\mu\text{F}

0.22\,\mu\text{F}

0.05\,\mu\text{F}

0.47\,\mu\text{F}
