What is the circuit symbol for resistor?
Scroll down to related links and look at "Symbols for a resistor".
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.
How do you find unknown value of a resistor when total resistor values and voltage are known in a series circuit?
A: If you know the total resistance and total voltage then you know total current flow for the circuit, this current will be same for every resistor in series however the voltage drop will change for each resistor . So measuring the voltage drop across the resistor in question and divide by the total current will give you the resistor value.
How is a resistor different from a fuse?
A resistor is a material that attenuates the current through a conductor. An insulator isolates the conductor from the surrounding material.
What is the purpose of a resistor in a regulated power supply?
Need more information - a typical regulated power supply would include dozens of resistors, each for one of several different reasons. Which resistor are you asking about?
What is the symbol for ldr?
The symbol for Light-Dependent Resistor (LDR) is a resistor symbol with photo-sensitive material added to one side. It looks like a regular resistor with one side having a shaded area to represent its light sensitivity.
What is the symbol of thermistor?
The symbol of a thermistor is a resistor with an arrow pointing towards it.
