A circuit does need resistance but not necessarily a resistor. without any resistance a circuit will be considered a "short circuit" and you power source will most likely overheat.
Resistance can be created in millions of different ways. This could be something such as an or any other light source but also a module such as a capacitor resistor or diode. To get to you're question more directly a circuit needs resistance to keep from shorting out. A specific module(such as an LED) would need a resistor to lower the voltage so to a point where the module can accept the power without burning out.

What type of resistor is used for automotive circuits?
Which type of resistor is commonly used in automotive circuits?
Why RC circuit is preferred over RL circuit in waveshaping?
There is no true advantage of RC circuits over RL circuits, as they perform different functions. RC circuits contain resistors and capacitors, while RL circuits contain resistors and inductors.
What will happen if you connect identical integrated circuits in series?
Connecting integrated circuits is not the same as the much simpler cases of resistors, capacitors, inductors, motors, light bulbs, etc. Integrated circuits have designated functions, and they operate in concert with the surrounding circuit design. As such, the idea of "connecting identical integrated circuits in series" has no meaning in the general case. You would need to state what kind of integrated circuit is involved.
How to design a phase shifter circuit using operational amplifier to have a desired phase shift?
There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
What is the function of a 180K resistor in hobby kit?
All resistors have the same function in a hobby kit, to cause a voltage drop in series circuits or reduce currents in parallel circuits. A value of 180k ohms is just going to do that by a lot.
Why do you need resistors?
Resistors are used for a variety of purposes: to allow voltage levels to be reduced when in series circuits, to bleed off capacitors, to assert the output level of tri-state or open collector microchips and to protect circuits from damage.
What are advantages of a series combination of resistors?
parallel combination of resistors are used in house circuits
What products use resistors?
allmost every electronic devices uses resistors..(it is needed in all circuits)
How do you wire Resistors required for led combination circuits?
in series
Can resistors function the same in AC circuits as in DC circuits?
Yes, they both can add a load to a circuit.
How do you install tail light on a Mazda bt-50?
Due to the complex nature of the system, Load Resistors will need to be fitted in both the indicator circuits and stop light circuits. Possibility of also requireing them in the park light circuits but not confirmed.

What is the relationship between you and R in networks of parallel resistors in electric circuits?
libolo
What protects circuits from dangerously large currents?
resistors circuit breakers fuses
What are the disadvantages of integrated circuits?
The disadvantages of integrated circuits include the limited range of IC resistors. Another disadvantage is that inductors cannot be formed using integrated circuits.
What kinds of circuits need precise resistors?
Timing circuits, and any circuit that depends on the resistor value being fairly precise, such as voltage dividers and comparators. Old story....engineers knew that you couldn't pick through a bunch of loose precision resistors to find close tolerance resistors....The manufacurer already took the close precision resistors and sold them separately. This is not so true these days. Even low tolerance resistors might be high precision. Usually the manufacturer will fill the loose precision needs with parts better than required.
