You can have electrical currents, or currents in fluids such as water or air.
Electrical currents in the brain are generated by the flow of charged ions, such as sodium and potassium, across neuronal cell membranes. These currents are essential for processes like communication between neurons and the regulation of brain activity. The intricate network of neurons and synapses in the brain allows for the transmission and processing of information through these electrical signals.

Electrical energy is the energy in electricity - mainly in electrical currents.
electrical currents
In fluids and in electrical circuits.
Electrical currents are a form of energy flow resulting from the movement of charged particles, typically electrons, through a conductor. This movement creates an electric charge that can perform work, such as powering devices or generating magnetic fields. Essentially, electrical currents are a manifestation of electrical energy in motion.
