It seems to me that Professor Shercliff is really focussing on transient conditions on switching on or off dc circuits and the operation of ac circuits. I notice the diagram does not include one or more switches therefore I would assume steady state conditions would be the purpose of the question. In any case even during the transient period, as I understand it, Kirchoff's laws apply at any specific point at any specific instant of time. Whether wanted or not every circuit has some inductance and some capacitance which have their effect during the transient period of microseconds or nanoseconds, but once the transient period is over neither has an effect in the steady state.

Just to add. My understanding is that Kirchoff's laws and equations apply to ac circuits if you add " at any given instant of time".

The circuit given is a dc circuit and a radio aerial only transmits when given an ac signal to create a magnetic field. Surely in a dc circuit Kirchoff's equations hold good ?

A night on Chinese food and beer in Singapore in the 1960's would ensure an ample sample............

This kind of problem I can be solved making simultaneous equations using Kirchoff's voltage and current laws. If you search " solving problems using kirchhoff's voltage and current equations" you should find the information you need " An alternative method applicable to this type of problem is known as the superposition theorem.

In computer architecture there are two forms of OR gates providing two different functions. They are the ""inclusive OR gate" and the "exclusive OR gate." The inclusive OR function provides an output when both inputs are present: the exclusive OR does not provide an output when both inputs are present. It seems to me that it is a matter of the definition of what "or" means within the context.

English is an ever evolving language. As a schoolboy one of the books I had to study for my English literature exam was Chaucer's Prologue to the Canterbury Tales. That would have been published late in the 14th century. Many words had a different but often vaguely linked meaning to those of the present day. Perhaps it is worth mentioning that Shakespeare (1564-1616) is credited with introducing or inventing over 1,700 words!

Dear Mister President, pleased to see that you have recovered from the run of disabilities that I read in the press prevented you from serving in the military during the Vietnam war. As for Afghanistan, like many in the UK I have known someone who gave his life. He was a 19 year old friend of my grandson. It so happens his last moments were filmed and can be seen in the following video which was made by a BBC crew who were making a documentary in Afghanistan at the time. "

Return "Mein Kampf" to the library and take out " How to win friends and influence people"

Being In aimless drift, the countryside I wander and where I roam my eyes perceive in wonder arrays of life within my sphere of being. Which makes me glad to be among the living. But was it chance that brought me into being, this heady mix of thoughtfulness and feeling; elation in the marvel of existence within these many forms of life’s persistence? And why should I among these forms of living think that my life was special in the giving? A mote of dust that wanders in infinity; a moment’s glow within endless eternity.

Today I learned of white rainbows and how they can be formed.

I Have a suspicion that in their dreams Tump would like to annex Greenland, Canada and South America. Putin would like to annex Europe and the United Kingdom and the Chinese would like to annex Taiwan, Japan and Indonesia.

I think I'll stop banging my head on the wall. I look forward to the time the whole world runs on free electricity

you seem to think that your generator will be more than 100% efficient. That would allow you to construct a perpetual motion machine. To save me wasting more time why don't you google "why can't a generator power itself". BTW you have already been told the law that forbids a machine being more than 100% efficient.
