Electric current and water current are similar in that they both involve the flow of a substance - electrons in the case of electric current and water molecules in the case of water current. Both currents can be controlled and directed through the use of circuits or channels. Additionally, both currents can generate power and be harnessed for various applications.
The flow of water is often compared to the flow of electric current. In both cases, the flow is the movement of a substance (water or electrons) from one point to another. The pressure difference in water systems is analogous to the voltage difference in electrical systems, and the flow rate in water systems is similar to the current in electrical systems.
Voltage in a circuit can be compared to water pressure in a pipe. Just like higher water pressure allows water to flow faster and with more force, higher voltage in a circuit enables electric current to flow more easily and with more energy. Conversely, lower voltage results in slower and weaker flow of electric current, similar to low water pressure leading to a weaker flow of water.

In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
This is a simile because it compares the flow of electric current to the flow of water in a river bed using "like."
Current
I've never tried it and I could be wrong but I believe you could pass an electric current through a vegetable, especially one with a high water content. Similar to how you can pass an electric current through a person.
It might be possible to characterize an electric charge as a current -- if that charge is moving. Any moving charge is electricity under the fundamental definition of that term. Electricity is generally thought of as moving electrons, but a more fundamental definition of electricity is any moving charge or group of charges. If your electric charge is moving, it is electric current.
Yes it does.

Sugar (sucrose) is a material that dissolves in water but does not conduct electric current. Sugar molecules do not ionize in water, so the solution does not carry electric charge.

Water.
an electrolyte
Yes, it will conduct electric current much better than plain water. The sugar molecules in water form a clear solution by ionization facilitating the path of electrons of electric current.
