A C=0.1µF (1µF=10-6F) capacitor is arranged so that a constant (does not depend on time) current of I=2 µA (1µA=10-6A) flows toward the top electrode, and away from the bottom electrode. How long will it take to charge the capacitor to 10V?

0.5 seconds

Explanation:

Charge

Resistance

We have the relation

The time taken is 0.5 seconds

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
