What else can I help you with?
The dimmer switch in a lighting circuit controls the brightness of one or more lamps by varying the resistance in the circuit what schematic symbol could be used to represent this device?
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.
A can be used to reduce the current in a circuit?
A resistor.
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
What is need of capacitor and resistor in circuit?
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.
What are the different symbol of resistor?
Put the resistor symbol ie zig zag. Then put a crossing line with arrow headed at the top.
What are devises run by electrical energy represented as resistors in a circuit?
Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.

What does a resistor do in an ampliflyer circuit?
what does a resistor in an ampliflyer circuit
Symbol for resistor?
-------------[_________]-------------- and put a line on the top of the box
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
How do you symbolically represent a conecting wire and a resistance?
The symbol for a wire is simply a line between circuit elements. The symbol for a resistor is a squiggly line. The related link goes directly to a picture of the symbol.
What parts of a circuit acts as a resistor?
Any part of a circuit that has a voltage drop across it is a resistor.
A can be used to reduce the current in a circuit?
A resistor.
What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
How do you show on a circuit diagram that the output on an electrical device can be varied?
To show that the output on an electrical device can be varied on a circuit diagram, you would typically use a variable resistor or potentiometer symbol. This symbol consists of a resistor with an arrow pointing inwards or outwards, indicating that the resistance can be adjusted. By connecting this symbol to the output component in the circuit, you demonstrate that the output can be varied by adjusting the resistance.
Does a resistor reduce current or voltage in an electrical circuit?
A resistor reduces the flow of current in an electrical circuit, which in turn affects the voltage across the resistor.
What is a single resistor the represents a complex circuit?
Equivalent Resistor
