An Series Circuit Consists of an Ac Voltage Source, a Resistor

question 169

Short Answer

An series circuit consists of an ac voltage source, a resistor of resistance $810 \Omega$ , and an inductor. (There is no capacitance in the circuit.) The current amplitude is $0.40 \mathrm {~A}$ , and $\mathrm { t }$ phase angle between the source voltage and the current has magnitude $11 ^ { \circ }$ .
(a) Does the source voltage lag or lead the current?
(b) What is the voltage amplitude of the source? he

Definitions:

Photosensitive

Having a sensitivity to light, causing a chemical, physical, or biological response when exposed to it.

Retinal Ganglion Cells

Neurons in the retina that receive visual information from photoreceptors via bipolar cells and transmit it to the brain.

Retinohypothalamic Tract

The retinohypothalamic tract is a pathway in the brain through which photic information travels from the retina to the hypothalamus, involved in the regulation of circadian rhythms.

Lateral Geniculate Nucleus

A vital relay center in the thalamus for the visual pathway, processing signals from the retina to the visual cortex.
