Resistors in a circuit reduce the flow of current by impeding the movement of electrons. This causes a decrease in the overall current flowing through the circuit.
Voltage is the force that causes current to flow through a circuit. In a similar way it isn't pressure that flows through a pipe - it is the fluid flowing through a pipe due to a difference in pressure at the entry and exit of the pipe that causes the fluid to flow through, no pressure flowing through a pipe.
As the blood moves through the aorta, the friction of the walls of the aorta decreases velocity. This velocity decrease results in a decrease in pressure.
It doesn't. The opposite is true. Blood pressure is proportional to blood volume. The greater the blood volume is, the higher the blood pressure will be. This is because there will be a greater volume of blood flowing through the blood vessels which means that a greater pressure will be exerted on the walls of the blood vessels, which means increased blood pressure.
The current through a material can be changed by varying the voltage applied across the material. By adjusting the voltage, you can increase or decrease the current flowing through the material. Additionally, changing the resistance of the material can also impact the current flowing through it.
If blood starts flowing backwards through a valve, stroke volume and ejection fraction would decrease. The heart's pumping action would be less efficient.
Voltage is the pressure that moves the electrons (current) through a circuit.
When oil flows through an orifice, the pressure on the upstream side (before the orifice) is typically higher than the pressure on the downstream side (after the orifice). This pressure difference is necessary to overcome the resistance to flow caused by the orifice's size and shape. As oil passes through the orifice, it accelerates, resulting in a decrease in pressure on the downstream side according to Bernoulli's principle. Therefore, the pressure on the upstream side will always be greater than the pressure on the downstream side during flow.
I think you are asking about hyper tension.
Decreasing the current flowing through the wire or increasing the distance from the wire are both ways to decrease the magnetic field around a wire. Adding a material that is not permeable to magnetic fields around the wire can also reduce the strength of the magnetic field.
As the balloon rises through the troposphere, the instrument will generally show a decrease in temperature and pressure with increasing altitude. The decrease in pressure will be more pronounced, leading to a drop in atmospheric density.
As pipe diameter increases, pressure decreases. This is because the same amount of fluid is flowing through a larger area, resulting in lower pressure.
