Does V=IR define resistance for any conductor?
This law is also not true for when you're dealing with EMI. Potential difference will be zero across a circuit yet a current will flow.
Rather use current density = conductivity * Electric field. (Th …

Can a wire having a $610$-$670$ THz (frequency of blue light) AC frequency supply, generate ...
Yeah definitely . You can create light corresponding on any frequency by this method. It’s just that creating this circuit will be very challenging. To give you a perspective, the highest frequency th …
