The Anode.
Think of the arrow like a Capital Letter A standing for the Anode.
In electrical engineering there are many types of symbols used to notate devices. These include symbols for polarity, switches, diodes, and batteries.
On a schematic diagram, an ammeter is typically represented by a circle with the letterAinside the circle.
asterisk
Use the standard resistor symbol and then place an arrow across the resistor. The bottom of the arrow midpoint of the resistor and just below, the tip of the arrow (draw with an arrow head) just above the resistor. This represents the wiper of the variable resistor.
In schematic diagrams for technicians: a circle with a V inside - or - a circle with a traditional analog meter pointer inside and the voltage or the function wirtten beside the symbol. In engineering or scientific experiement diagrams, a circle with an E inside. Expect to find several variations of this symbol throughout your career..
