What else can I help you with?
Why are insulators of electricity used to prevent electric shock?
Insulators prevent electric shock by blocking the flow of electricity. They do not conduct electricity, so they do not allow the electric current to pass through them and into the body. This helps to protect individuals from coming into direct contact with the dangerous current.
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.
Is it true that an alternating current passing through a capacitor While a direct current can not Explain?
Then I'll try this. Just as V=IR is the fundamental equation relating voltage, current and resistance for a resistor circuit, the following equation relates voltace, current and capacitance for a capacitor: Or, if you are not familiar with that calculus term with the derivative, you can think of it as: I(t) = C * (change of voltage per time) So when you have DC, there is no change of voltage with respect to time, so there is zero current. When you have an AC voltage signal that varies across the capacitor with time, that equation lets you calculate the current that results through the capacitor. A capacitor is two surfaces near each other, but not touching. A direct current "sees" a capacitor as an open switch. It cannot pass through. An alternating current "induces" a charge in a capacitor and can pass through.
Current that doesnt reverse direction is called?
direct current
What is the difference between Direct Current positive and Direct current negative?
Direct Current Positive - the starting point at which the electrons flow through the wire circuit. These electrons are fully charged, ready to expend their energy into the various points in the circuit, be it a lightbulb etc Direct Current Negative - the return point of the finished electrons into the battery to collect more energy to enter the circuit again.
What is commutation circuits?
the process of reversing the current through individual armature coils, and then conducting the direct current to the external circuit during the brief interval of time each commutator segment is passing under a brush
How can you tell if a line is the graph of a direct variation?
It is a straight line passing through the origin.
How can you tell of a line is the graph of direct variation?
It is a straight line passing through the origin.
How is electrolysis of water used?
Electrolysis, passing an electric current, through water separates the water into its elements: oxygen and hydrogen. When Direct Current (DC) is used, oxygen precipitates (comes out of) the water at the positive electrode and hydrogen precipitates at the negative electrode.
Is it true the alternating current can pass through a capacitor while the direct current cannot pass through?
Yes.
What does passing sunlight through a prism do?
Color is a direct function of light by passing sunlight through a prism and observing the bands of spectrum of colors was discovered by Isaac Newton. It was discovered in the 1660's.
Clearly state the definition of electrolysis?
Electrolysis is a chemical process where an electrolyte is chemically decomposed into its consituents by passing an direct electric current through it inside an electric cell.
Can earth fault current go up passing through the downstream panel and directly cause a trip at the upstream panel which have higher set point of earth fault protection?
If the fault is a direct short to ground, the fault current can be high enough to trip the upstream protection.
List and describe the two main electric modalities or current used in cosmetology?
Galvanic- a constant and direct current, having a positive and negative pole and produces chemical changes when passing through the tissues and fluids of the body Telsa High Frequency current- heat producing current with a high rate of oscillation or vibration
What is the electric current from a battery?
The electric current from a battery is the flow of charged particles, typically electrons, through a circuit. The current is measured in Amperes (A) and represents the rate at which charged particles move through the circuit. It is essential for powering electronic devices and creating electrical circuits.
Why are insulators of electricity used to prevent electric shock?
Insulators prevent electric shock by blocking the flow of electricity. They do not conduct electricity, so they do not allow the electric current to pass through them and into the body. This helps to protect individuals from coming into direct contact with the dangerous current.
What is electrolysis simple answer please thanks?
The passage of direct current through an ionic liquid (either molten OR dissolved in something (often water). The idea is that the current causes the positive AND the negative ions travel in opposite directions - and thus can be separated.
