It can be anything, as long as it's clearly defined in accompanying text.
The most commonly used is ' I '. Current has the units of Amperes.
The symbol for a rheostat is a resistor with an arrow indicating a variable resistance that can be adjusted by a knob or slider. It is commonly used in electronic circuits to control the flow of current.
In electrical work, resistance is often represented by the symbol "R" and is measured in ohms (Ω). It describes how much a material or component impedes the flow of electric current. The higher the resistance, the more difficult it is for current to flow through a circuit.
Those are two different things. Here are the answers to both: -- There is no such thing as a "flow of power". -- The flow of electric charge is "electric current".
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
The ampere (symbol: A) is the SI Base Unit for electric current, and is defined in terms of the force between two, parallel, current-carrying conductors.

Resistance to current flow is measured in ohms, denoted by the symbol Ω. It quantifies how much a material or component impedes the flow of electric current through it.
The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
THE SYMBOL FOR Flow Meter is : FI as Flow Indicator
The symbol "i" is used for electric current because it stands for intensity, which relates to the flow of charge in a circuit. It is a convention established over time in the field of physics and electrical engineering to represent electric current in equations and diagrams.
The above is the symbol of flow meter.
The Underline below symbol G represent about flow of current,if the line is straight it shows direct current,and if it is zig-zag then it is alternate current.
The symbol usually used inside a circle to designate a current source is an arrow pointing outward, indicating the direction of conventional current flow. This symbol is often accompanied by a circle to represent the source itself, distinguishing it from voltage sources, which typically use a different symbol. In circuit diagrams, this notation helps clarify the role of the current source in the circuit.
The symbol for a rheostat is a resistor with an arrow indicating a variable resistance that can be adjusted by a knob or slider. It is commonly used in electronic circuits to control the flow of current.
AmperesAnother AnswerThere really is no such thing as a 'rate of current flow'; if it existed, then it would be expressed in amperes per second.
The measure of how much a material opposes the flow of current is called resistance. It is measured in ohms and is represented by the symbol Ω.
A Counter-current flow has more advantages as comapared to a co-current flow.
