Question 1

Does Ohm's law work for all components?

Accepted Answer

Ohm's law is ideal for resistors. Other components like capacitors and inductors follow frequency-dependent relationships.

Question 2

Why is division by zero an issue?

Accepted Answer

If resistance is zero, current is theoretically infinite in an ideal model. Real circuits include internal resistance and limits.

Question 3

Is this for AC or DC?

Accepted Answer

This simplified version typically assumes DC resistive behavior. AC circuits can require additional modeling for impedance.
