Multiplier

Hi, in big essay questions with lots of marks when I'm explaining how the multiplier changes national income, would I HAVE to explain it with an example e.g. if consumer expenditure increases the multiplier will operate by so and so....


What I mean is, how can I explain the multiplier in general terms without having to refer to specifically consumption/investment/government/X-M?
Thank you.
We only have to mention the multiplier effect rather than explain for WJEC.
Generally I would describe it as the increase in final income arising from any new injection of spending

I would define it as followed:

When an initial injection into the circular flow leads to a greater than proportional increase in national income. .., Eg, one persons spending is another persons income.
