- 3. Multiple Choice
In the below figure for capacitors connected in parallel, what is the correct statement and formula ?
The Total charge will be the sum of the charges in each of three capacitors QT=Q1+Q2+Q3
Charge in each capacitor is the same QT=Q1=Q2=Q3
Charge in each capacitor is different but current in each capacitor are the same
The total charge will be QT=Q1- Q2 - Q3
- 4. Multiple Choice
For capacitors connected in series the Total voltage are expressed by the formula of ?
VT=V1+V2+V3
VT=V1=V2=V3
