Example 2: A 47-μF capacitor is charged by the voltage sources having the following waveform. Determine the charging current. Refer to Fig. 2.100. Assume that the voltage source is ideal and has no resistance.
FIGURE 2.100
Answer: Since dV/dt represents the slope of the waveform, it is simply 10 V/10 ms, and the current becomes:
Example 3: If the voltage across a 100-μF capacitor is 5 V e−t, what is the capacitor current?
Answer:
(Remember, these ...
