Imagine you switch on any plug. Assume the current is active through the wire.
We know the voltage is what forcing unit charges to pass the electric impulse which is formed as current. The phonon vibrations creates the resistance.
Now close your eyes and imagine this whole process visually.
How will be the impulse be travelling? How will be them carrying in that conductor?
How will be the phonon vibrations hindering their motion?
What is the voltage/potential doing?
Now after this,
Just imagine the same process.
How does a radiation,passing through a media/vacuum.
