The inverse measure is known as electrical conductance.
High resistance flow. Substances in which electricity can flow are called conductors a piece of conducting material of a particular resistance meant for use in a circuit is called a resistor conductors are made of high conductivity materials such as metals in particular copper and aluminium resistors on the other hand are made of a wide variety of materials depending on factors such as the desired resistance. It can be due to static or dynamic load. High electrical resistance is the opposition to current flow within a circuit. Resistance refers to the property of a substance that impedes the flow of electric current.
Some substances resist current flow more than others. The length of a vessel is directly proportional to its resistance. Resistance is measured in ohms symbolized by the greek letter omega ω. All conductors give off some degree of heat so overheating is an issue often associated with resistance.
My ob gyn did not seem much bothered by this. Resistance is the measure of opposition to electric current. I m in 20th week of pregnancy and during anomaly scan although the baby appeared fine radiologist noted that there s higher than normal resistance in both uterine arteries. Ohms are named after georg simon ohm 1784 1854 a german physicist who studied the rela.
The lower the resistance the higher the current flow. The longer the vessel the greater the resistance and the lower the flow. If its resistance to current flow is very low it is called a conductor. Is electric motor load.
A short circuit is an electric circuit offering little or no resistance to the flow of current. Short circuits are dangerous with high voltage power sources because the high currents encountered can cause large amounts of heat energy to be released. Vascular resistance is the resistance that must be overcome to push blood through the circulatory system and create flow the resistance offered by the systemic circulation is known as the systemic vascular resistance svr or may sometimes be called by the older term total peripheral resistance tpr while the resistance offered by the pulmonary circulation is known as the pulmonary vascular. If a substance offers very high resistance to current flow it is called an insulator.
Static load can be resistor heating coil etc. Electrical resistance explains the relationship between voltage and current. Resistance is a measure of the opposition to current flow in an electrical circuit. Dynamic load for e g.
As with blood volume this makes intuitive sense since the increased surface area of the vessel will impede the flow of blood. It is nothing but opposition to the current flow. She has prescribed ecosprine 75 till 32 weeks. Low resistance allows more current to flow and vice versa.
She also suggested having doppler scan in 10 days. The higher the resistance the lower the current flow.
