c) Charge and energy
d) Conductance and inductance

Answer 1

To determine the minimum and maximum values for capacitors, you need to consider the variables involved, such as voltage, current, resistance, capacitance, charge, and energy. The maximum and minimum values for each variable depend on the specific situation and formulas related to capacitors.

Step-by-step explanation:

a) To determine the minimum and maximum values of voltage and current between points A and B for capacitors, you need to consider the voltage and current formulas:

1. The minimum voltage is 0V, as there is no potential difference between the points. The maximum voltage is given by the equation V = Q/C, where Q is the maximum charge on the capacitor and C is the capacitance.
2. The minimum current is 0A, as no current flows if there is no potential difference. The maximum current is given by the equation I = dQ/dt, where dQ is the change in charge and dt is the change in time.

b) To determine the minimum and maximum values of resistance and capacitance between points A and B, you need the formulas:

1. Resistance is not directly related to the capacitors, so the minimum and maximum values are not applicable.
2. The minimum capacitance is 0F, as there is no capacitor present. The maximum capacitance is the sum of the individual capacitances for all capacitors in the circuit.

c) To determine the minimum and maximum values of charge and energy between points A and B, you can use the formulas:

1. The minimum charge is 0C if there is no capacitor present. The maximum charge is given by the equation Q = CV, where C is the capacitance and V is the voltage across the capacitor.
2. The minimum energy is 0J if there is no capacitor present. The maximum energy is given by the equation E = 0.5CV^2, where C is the capacitance and V is the voltage across the capacitor.
3. d) Conductance is not directly related to the capacitors, so the minimum and maximum values are not applicable. Inductance is also not applicable in this context as it is related to inductors, not capacitors.
