A flow of electrons is needed to have a current.
And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit.
All tied up in Ohms Law - which I'll leave to you.

What are 2 main parts of an electrical current?
battery and a switch
What damages a rectifier?
Rectifiers are electrical parts, all electrical parts are rated for 3 things. 1) voltage 2) current 3) temperature Exceed any of these things and the electrical part will fail.
Current electricity vs electrical current?
Current or "electrical current" (to distinguish it from current in a river) is the flow of electrons in a wire which can perform useful work. The current can be generated by a battery or a generator, or by other means. Current electricity is not a commonly used term. "Current electricity" is the science of electric currents, and it means the same thing as Electrodynamics. Example: the Electrical Sciences can be divided into two parts: Static Electricity or Electrostatics, and Current Electricity or Electrodynamics.
What is he definition of electrical current?
The current flowing in an electrical circuit.
What is kind of electric light?
Lightning is an electrical current that starts in clouds due to differences in electrical charges between parts of the clouds.
What is the purpose of Slip Rings?
To facilitate the conveyance of electrical current and/or signals between the static and rotating parts of a device.
What are the three main parts of a cable?
The three main parts of a cable are the conductor, which carries the electrical current; the insulation, which encases the conductor to prevent electrical leakage; and the sheath, which provides protection and durability to the overall cable structure.
How does a pressure to current converter works?
An electrical circuit is an example of an electrical pressure to electrical current convertor.
Difference between electrical current and electrical charge?
current is the flow of charge.
What is the connection of all exposed non-current-carrying metal parts to the earth?
The connection of all exposed non-current-carrying metal parts to the earth is known as grounding. This practice is essential for safety, as it helps prevent electric shock by providing a low-resistance path for fault currents to safely dissipate into the ground. By connecting these metal parts to the earth, it ensures that in the event of a fault, the electrical current will be directed away from users and reduce the risk of electrical fires or equipment damage. Grounding also helps stabilize voltage levels in electrical systems.
What electrical current flows through electrical home devices?
The electrical current for a home device travels in a circuit.
What is dynamic current?
it is a flow of charge practically from negative to positive terminal
