If the charge on an isolated conductor is negative, is it's

Click For Summary
When the charge on an isolated conductor is negative, its capacitance remains positive despite the negative charge. This is because capacitance is defined as the ratio of charge (Q) to voltage (V), and a negative charge will correspond with a negative voltage. However, since capacitance is a measure of the ability to store charge per unit voltage, it is always a positive value. Therefore, even with a negative charge, the capacitance does not become negative. The relationship between charge and voltage ensures that capacitance remains a positive quantity.

If the charge on an isolated conductor is negative, is it's capacitance negative by the formula C = Q / V??

No because V would also be negative.
 

Thread 'What determines if wave components are independent vs coherent?'

I'm working through something and want to make sure I understand the physics. In a system with three wave components at 120° phase separation, the total energy calculation depends on how we treat them: If coherent (add amplitudes first, then square): E = (A₁ + A₂ + A₃)² = 0 If independent (square each, then add): E = A₁² + A₂² + A₃² = 3/2 = constant In three-phase electrical systems, we treat the phases as independent — total power is sum of individual powers. In light interference...
