A coil has an inductance of 2.00 mH, and the current in it changes from 0.200 A to 1.50 A in a time interval of 0.150 s. Find the magnitude of the average induced emf in the coil during this time interval.

0.0173 V

Explanation:

PARAMETERS GIVEN:

Inductance, L = 2 mH = 0.002 H

Time interval, dt = 0.15 s

Change in current, dI = 1.5 - 0.2 = 1.3 A

The magnitude of the induced EMF is given as:

EMF = | -L*dI/dt |

EMF = (0.002 * 1.3) / 0.15

EMF = 0.0173 V

0.0173 V

Explanation:

The Emf induced in a coil is given as

E = Ldi/dt Equation 1

Where E = Emf induced in a coil, L = Inductance of the coil, di = change in current, dt = time interval/change in time.

Given: L = 2.0 mH = 2×10⁻³ H, di = 1.5-0.2 = 1.3 A, dt = 0.15 s

Substitute into equation 1

E = 2×10⁻³(1.3/0.15)

E = 1.73×10⁻² V

E = 0.0173 V

Hence the emf induced in the coil = 0.0173 V

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
