Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phenomena and post it here.

Unlike the idealized voltmeter, a real voltmeter has a resistance that is not infinitely large. part a a voltmeter with resistance rv is connected across the terminals of a battery of emf e and internal resistance r.

The acceleration of an object is the slope of its velocity-time graph. True False
