Consider an RC circuit with a capacitance of 150 0F,a resistance of 1 MΩ and connected to a 200-V power source for a long time.The power supply is disconnected and shorted.How long should one wait before the voltage across the capacitor drops to below 50 V?
Unexpected Panic Attacks
Sudden episodes of intense fear or discomfort that arise without warning and without an apparent trigger.
Panic Attacks
Sudden episodes of intense fear or anxiety, often accompanied by physical symptoms such as heart palpitations, shortness of breath, or dizziness.
Specifiers
Further descriptors of a patient’s condition that capture the natural variation in the expression of affective disturbances, and therefore increase the specificity of diagnoses by conveying important information about salient features that might be otherwise overlooked.

Specific Phobia
An intense, irrational fear of specific objects, situations, or activities that poses little to no actual danger.
