In a word - yes.
add There are valves in the heart and in the veins, and in addition there are tiny structures precapillary sphincters, which control the flow from the arteriole (little artery) to the capillaries which then become venules (tiny veins).
A diode restricts the direction of movement of charge carriers in an electronic circuit. It allows current to flow in one direction (forward bias) but blocks it in the reverse direction (reverse bias). By controlling the flow of current, diodes are essential for rectifying and regulating voltage in electronic devices.
In an AC circuit, the direction of current alternates back and forth periodically. This means that the current flows in one direction for a period of time and then reverses its direction, completing one cycle. This back-and-forth movement of current is what allows electrical devices to operate consistently and efficiently.
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
direction of magnetic field
A negative answer in a Kirchhoff's Current Law calculation indicates that the assumed direction of current flow was incorrect. It suggests that the actual direction of current flow is opposite to the assumed direction. Therefore, the sign of the calculated current should be corrected to reflect the actual flow direction.
No. A resister is not a replacement component for a diode. A resister is passive and allows current to flow through in in both directions. A diode is a single semiconductor junction that only allow current to flow in one direction.

As induced magnetic lines exist in a plane perpendicular to the direction of flow of current, the component in the direction of current i.e cos 90 component will be zero. Recall cos 90 = 0. Hence the answer
A diode is an electronic component which only allows the current to pass through it in one direction. This is useful in many aplications, such as preventing current to flow in the wrong direction in a circuit. A resistor is also an electronic component, but instead of preventing the current from moving in a certain direction the resistor creates an electrical resistance which will effect the current passing through it. The larger the resistance of the resistor, which is measured in Ohm, the greater the effect it will have on the current.
You cause the current to flow through an electronic device that allows current to flow in one directionbut not in the other direction. Such a device is called a "diode" or a "rectifier".
A valve allows flow in only one direction. Diodes allow electrical current to flow in one direction only.
A device that changes the direction of the current is called a "switch" or a "reversing switch." This device allows for the current to flow in different directions as needed.
When the flow of current is aways in one direction it is known as direct current.
Not in normal circumstances. A diode is an electonic device that allows current to flow freely in only one direction.
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.
