Can inserting a resistor in a circuit produce an effect similar to a open circuit?

Of course it depends entirely on the ohm's resistance of the resistor. The higher the resistance, the lower the comparison to a short circuit.

What is meaning of RLC?
RLC circuit(or LCR circuitorCRL circuitorRCL circuit) is anelectrical circuitconsisting of aresistor, aninductor, and acapacitor, connected in series or in parallel. The RLC part of the name is due to those letters being the usual electrical symbols forresistance,inductanceandcapacitancerespectively. The circuit forms aharmonic oscillatorfor current and willresonatein a similar way as anLC circuitwill. The main difference that the presence of the resistor makes is that any oscillation induced in the circuit will die away over time if it is not kept going by a source. This effect of the resistor is calleddamping. The presence of the resistance also reduces the peak resonant frequency somewhat. Some resistance is unavoidable in real circuits, even if a resistor is not specifically included as a component. A pure LC circuit is an ideal which really only exists in theory
What is a surge resistor?
A surge resistor is a resistor installed in a circuit to prevent a "surge" when conditions arise where a surge might occur. That might be a bit wordy, but that's the answer. Let's look at an instance where a surge resistor is used and see how it works. There are a number instances where energizing a circuit is followed by a surge of current. Like almost all the time. When that circuit "comes on" after the switch is flipped, current is flowing. And sometimes we need to place a resistor in series with the component or components that want to draw a ton of current on startup. We can look at a component that might just do that. Capacitors (caps) are sometimes fitted with something that limits a big shot of current when a circuit is energized. Caps, you recall, begin operation in the circuit of a modern equipment uncharged, and when these caps are first "seen" by the voltage source at the moment it's turned on, they look like a short circuit. Lots of current may want to flow. Jumping ahead, the cap sits in the operating circuit fat, dumb and happy "using" only a little current after things are going. But at startup, it needs to be checked to prevent it from "sucking up" (or sinking) too much current and overloading the supply. The surge resistor is on the job each time the circuit is energized. There are other applications for a surge resistor, but the purpose is the same - prevent "too much current" from flowing at a given moment so the circuit can transition into a "normal operating mode" (where current flow is more modest). The surge resistor is similar to a so-called current limiting (or, perhaps, ballast) resistor, but the name applied to the resistor in question might have more to do with the specific application.
What are resistors in IC made of?
Resistor in IC are made of semiconductor structures in a manner similar to transistors and PN junctions
Application of electrical circuit analogies in magnetic circuit?
Magnetic circuit follows equation (4) that is Ni = (Ф) ( l / μA) or m.m.f(magneto motive force) = (Flux) (reluctance).Electric circuit follows ohm's law that is E = I.R or e.m.f(electro motive force) = (current) (Resistance)From above point m.m.f in magnetic circuit is like as e.m.f in electrical circuit.Flux in magnetic circuit is similar as current in electrical circuit.Reluctance in magnetic circuit, S = ( l / μA) is similar to resistance R = (ρl/A) in electric circuit.Permeance (= 1/reluctance) in magnetic circuit is equivalent to conductance (=1/resistance) in electric circuit.In magnetic circuit flux establishes but not flow like as current in magnetic circuit.In magnetic circuit energy needed only to establish the flux but no consistent energy need to maintain it whereas in electric circuit continuous energy needed to flow of current.Resistance of an electric circuit is constant (for same temperature) and is independent of current but reluctance of magnetic circuit is not constant because it depends on μ (=B/H) which is not constant and depends on B/H.
Difference between open and short circuit?
An open circuit has a break in it somewhere, so the circuit is not complete and electricity cannot flow. When you power off a light, for example, with an on/off switch, you open the circuit, turning off the light as desired. When there is an unwanted open circuit, for example from a damaged wire, the device or system is unpowered and cannot operate. A short circuit has some unwanted contact between points at different voltage levels, such as from hot to neutral or ground, or between positive and negative. When a short is in a circuit, electricity will take only that path of little or no resistance. The rest of the system is deprived of power, and the conductors feeding the point of the short will likely overheat or burn unless a fuse or breaker operates, creating now an open circuit.
Can inserting a resistor in a circuit have an effect similar to an short circuit?
It creates an extra load to the circuit if placed parallel to other circuits. this load approaches the equivalent of a short circuit as the resistance value placed there reduces.
Can inserting a resistor in a circuit have an effect similar to an open circuit?
If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.
What a device that protects an electric circuit from too much current?
Circuit Breakers and Fuses limit the amount of current flowing through the circuit.
What is the use of resistors in a circuit?
One use is as a current limiter. For example if a certain device (like a capacitor) is capable of being in conditions similar to a short circuit, the amount of current "drawn" by the capacitor could be damaging to it or other components. Placing a resistor in series with the capacitor means that you can select the proper resistor so that at maximum capable volt, you know the maximum current that will flow through that value resistor according to Ohms Law. Another use is to design to have a desired voltage present in certain parts of the circuit.

How are open circuit and closed circuit similar?
Not similar at all. They are opposites.

Does a motor work?
A motor does not provide energy. It converts electrical energy to mechanical energy. From a circuit standpoint, the motor is considered a load (similar to a resistor). Resistors convert electrical energy to heat energy.
What body system is similar to an electrical circuit?

How does a resistor in a circuit effect similar to open circuit?
Resistors resist amounts of the electricity flowing through the circuit.For example if the resister has these strips of colors on it in this order(red,green,blue) then the resister has 25,000,000 ohms. That means that the lamp(s)/ bulb(s) is(are) going to be very going to be very dim. Because, the more ohms the dimmer the light, the less ohms the brighter the light. But we should get back on task. A resistor effects a circuit because it makes the lamp(s)/ bulb(s) brighter of dimmer depending on the amount of ohms they have.
