5 FAQs about [Switch has stored energy mark]
What happens when a switch is closed?
The switch in the circuit shown has been open for a long time. At t = 0, the switch is closed. Once switch is closed, currents will flow through this 2-loop circuit. KVR and KCR can be used to determine currents as a function of time. Determine currents immediately after switch is closed.
What happens when a battery switch is closed?
My physics teacher said that the answer is B, and explained that after the switch is closed the electrons on the right side of the capacitor will move to the other side of the capacitor, and this current will cancel some of the current coming out of the battery, thus reducing the total energy stored in the capacitor.
How do you determine current when a switch is closed?
At t = 0, the switch is closed. Once switch is closed, currents will flow through this 2-loop circuit. KVR and KCR can be used to determine currents as a function of time. Determine currents immediately after switch is closed. Determine voltage across inductor immediately after switch is closed. Determine dIL/dt immediately after switch is closed.
What happens if a switch is opened after a long time?
After a long time, the switch is opened, abruptly disconnecting the battery from the circuit. What is the current I through the vertical resistor immediately after the switch is opened? Why is there Exponential Behavior?
What happens if an inductor sparks a switch?
What happens in the real world is that the inductor creates enough emf to form a spark in the switch. This means the switch no longer acts like an ideal switch. In the real world, we call this effect "flyback.". It can damage components, so we typically design circuits to prevent this from occuring.
