6 FAQs about [Store energy after closing or opening the switch]
What happens when a switch is closed?
When the switch is closed, the current that points right-to-left for the inductor increases in the direction of the loop. As a result of Faraday's law, the inductor becomes a "smart battery" that acts to reduce the current, which means there is a voltage drop: Einductor = −LdI dt (5.4.8) (5.4.8) E i n d u c t o r = − L d I d t
What happens after switch S1 is closed?
Immediately after the switch S1 is closed: After current through the right resistor immediately after switch 2 is closed? IR = 0 B. IR = V/3R A circuit is wired up as shown below. The capacitor is initially uncharged and switches S1 Now very long time? VC = 0 The capacitor will become fully charged after a long time.
What is a closed switch?
A closed switch is one that provides a direct (low resistance) path for current to flow through. How do you find the current when the switch is closed? Can a circuit work without a switch?
What is the difference between open and closed switch?
The terms “open” and “closed” are used to describe both switches and whole circuits. An open switch is one that has no continuity, meaning that no current can flow through it. A closed switch allows the current to flow in a direct (low resistance) path. Which switch when closed will cause a short circuit? What will happen after closing the switch?
What happens if a switch is 'on' or 'off'?
When a switch is in the ‘on’ position it allows the electricity flow to enter the main electrical circuit and the circuit becomes a closed circuit. On the other hand,when a switch is in the ‘off’ position it blocks the electricity flow from entering the main electrical i and the circuit becomes an open circuit.
What happens if a switch status is changed?
As soon as the switch status is changed, the capacitor will act as short circuit for an infinitesimally short time depending upon time constant and after being in that state for some time it'll again continue to behave as open circuit.
