Resistors "resist" current flow. The ultimate "blocking" resistor is an open circuit, having a resistance of infinity (for all practical purposes) ohms.
Capacitors also resist a change in voltage drop. For the case of a DC circuit, a capacitor, after reaching equilibrium, will present a DC resistance of infinity. For the case of the AC circuit, a capacitor will allow the AC signal to pass, while blocking any DC bias that might be present.
So, resistors and, in the DC case, capacitors, block current flow.

Comparison of Counter-current flow and parallel flow?
Counter-current flow is more efficient then parallel flow. Shahzad, MUET Chemical Engineer
Where are circuits used?
Circuits are used anywhere you want to have an electrical current flow. Without a circuit, you cannot have current flow. Without current flow, you cannot do any work.
What is a conventional current?
Conventional current shows current flow from + to - amp meters are labeled this way (conventional current flow) (hole flow) Physics shows that electrons are moving or flowing from - to + (electron flow) Tubes (deforest valves) sort of blew conventional current away semiconductors with different doping materials confuse it more so most new books relate to electron flow voltmeters ammeters are labeled the same since the 18th century
Difference between electron flow and conventional current?
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
If current flow in both direction in mosfet?
Do you mean "can current flow in both directions"? In theory, yes.
What happens to voltage when a reactor limits current?
the currents path blocks & normal voltage will flow
Is an unidirectional device that blocks the current flow from cathode to anode?
No, a unidirectional device that blocks current flow from cathode to anode is typically referred to as a diode. Diodes allow current to flow in one direction only, from anode to cathode, while blocking it in the reverse direction. This property is essential in various electronic applications, including rectification and signal modulation.
What substance blocks the flow of electricity?
Insulators, such as rubber or plastic, are substances that block the flow of electricity by preventing the movement of electrons. These materials have high electrical resistance, which hinders the flow of electric current through them.
What is the behavior of the current through a capacitor in steady state?
In steady state, the current through a capacitor is zero because the capacitor blocks the flow of direct current (DC) once it is fully charged.
What current does a capacitor pass?
ac power (alternating current) it blocks dc power Many people will say a capacitor can't pass current because they consider Electric current to be the flow of electrons but that's not necessarily the case. In a capacitor current is passed by the building up and dropping of an electric field. DC does not flow for long of course.
Can series circuits work when a switch is open?
No. Since the switch is in series with the circuit, opening it blocks the current flow through the circuit, turning it off.
How does a switch control a parallel circuit?
In a parallel circuit, each branch has its own pathway for current to flow. A switch placed in one branch of the circuit can control the flow of current through that specific branch only, without affecting the other branches. When the switch is closed, it allows current to flow through that branch; when it's open, it blocks the flow of current.
What are the advantages of co-current flow?
A Counter-current flow has more advantages as comapared to a co-current flow.
Are wooden blocks conductor or insulator?
Wooden blocks are insulators because wood is a poor conductor of electricity. This is because wood contains a high proportion of non-metallic elements that do not easily allow the flow of electrical current.
What is a current flow restrictor?
A current flow restrictor is a diode.
What blocks the flow of electricity?
The flow of electricity can be blocked by insulators, which are materials that do not allow electric current to pass through them. Some common insulators include rubber, plastic, and glass. Additionally, breaks or interruptions in the electrical circuit can also stop the flow of electricity.
What allows current to flow in one direction?
A diode is one of the fundamental building blocks of electronics. They allow the flow of electrons in one direction only. Thus are commonly used as rectifiers to turn ac voltages into dc. [A dry cell (mistakenly called a battery, which is a group of cells) will allow electron flow in one direction only, or rather, it will provide current flow in one direction. ]
