Current flow. It's also worthy of noting that a resistor doesn't limit-by, it limits-to, and the current is dependent on the voltage.
I[A] = U[V] / R[ohm]
It's also worth to note, that the power flowing through said resistor with resistance R is I[A] * U[V] for DC circuits - helps to remember this well when picking appropriately-rated resistors for replacement.
Example: let's say we have a 20-ohm, 2W resistor. If we place it in a circuit with 5V, we will get 5V / 20ohm = 250mA (0.25A) of current flowing through the resistor. The power the resistor will "see" is 250mA * 5V = 1.25W, so it's safe.
But let's now put that same resistor in a 12V circuit. The current flowing will be 12V / 20ohm = 600mA (0.6A), and the power will be 600mA * 12V = 7.2W, so the resistor will burn.

In a DC circuit . . . resistance. In an AC circuit . . . impedance.
a common cause of this type problem is corrosion at a connector.
Colector resistance in an emitter follower circuit serves to place a limit on how much current can be supplied by the transistor. Often, the resistor is sized so that a short circuit in the load does not cause the transistor to fail.
I think it is due to the resistance to the electrical appliance, the resistance offered by the electrical appliance works as a load in the circuit and when load is removed it causes sparking.
The electrical resistance of the circuit
When the circuit needs the electrical property of resistance, of course.

lowers the amt of electrical current flowing through it.
Of the three choices, capacitance does not limit current flow in an AC circuit.
Resistance, or electrical resistance. The SI unit is the ohm.

Resistance in an electrical circuit or device measured in ohms.
No. Resistance does not flow. Resistance is the characteristic of a material that resists the movement of electrons and thus the flow of electrical current.
It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
