If the voltage across the first capacitor (the one with capacitance C) is ΔV1, then what are the voltages across the second and third capacitors?

1/2 delta. V1 and 1/3 delta V1

Double the resistance of the resistor by changing it from 10 Ω to 20 Ω. What happens to the current flowing through the circuit?

The current decreases by a factor of two

Describe the effective capacitance when capacitors are connected in series

When capacitors are connected in series, the effective capacitance is LESS THAN the smallest capacitance

as we add resistors to a parallel circuit,

the overall resistance of the circuit drops, when resistance decreases, current must increase
