Find the charges on the three capacitors connected to a battery as shown in figure. Take C1 = 2.0 μF, C2 = 4.0 μF, C3 = 6.0 μF and V = 12 volts.
Redraw the circuit given
Given
Capacitance of C1 capacitor =2μF
Capacitance of C2 Capacitor =4μf
Capacitance of C3 capacitor =6μF
Voltage V=12V
Formula used
All three capacitors are in parallel. When capacitors are in parallel, we will add them.
Equivalent Capacitance
Charge of a capacitor can be calculated by the for formula
Where
Q is the charge of the capacitor
Ceq is the equivalent Capacitance of the capacitor
V is the voltage or potential difference across the plates of the capacitor
Charge on capacitor C1 is
Coulombs
Charge on capacitor C2 is
Charge on capacitor C3 is
Charge on capacitors 2μF, 4μF and 6μF are 24C, 48C, 72C respectively.
