What is an example of a capacitors in parallel practice problem?
Here is a practice problem for you. Attempt it and then I will help you if you battle on it.
Suppose 3 capacitors of values 22 nF, 220 nF and 2200 nF are all 3 connected in parallel to the same DC source voltage of 20 V. Calculate :
- The total capacitance of the entre circuit.
- The charge stored in each capacitor.
Suppose now that the capacitor network is discharge through a 1 mega 0hm series resistor. Determine the voltage over the resistor, and current through the resistor, exactly 1,5 seconds after discharge begins.
Suppose now that the same 3 parallel capacitors are now placed in parallel with an AC voltage source of RMS value 220 V, frequency 50 Hz. Calculate the total impedance of the circuit as well s the total current drawn from the AC source.
