Answer:
initially- with positive potential differences - the current is directly proportional to the p.d. However, as the current through the filament increases, the heating effect caused in the lamp also increases and so the temperature of the filament rises. This increase in the filament's temperature also increases the resistance of the filament. As a result the rate of increase of the current decreases and a greater change in the potential difference is required to cause a change in the current. This can be seen on the curve as the gradient becomes more shallow (greater resistance). This same pattern is repeated when a negative potential difference is applied across the filament

Answer:
The redshift data does not support the Big Bang Theory and without the redshift interpretation favored by the Big bang, there is no Big Bang.
Edwin Hubble did not believe that the redshift indicated expansion. Hubble saw the redshift as an hitherto unrecognized principle of nature. The redshift is the effect of centripetal force mv2/r = mv2/ct = v/c(mv/t) = v/c(p/t)= (v/c)m
The unrecognized principle of nature is the refraction effect of gravity on light.
n=c/v or v= c/n.
The Universe is older than 13.7 Billion years, likely around 16.5 billion years.
The proper law of Gravity is W = -mGM/r + cmV = -mu/r + cP where cP is the so-called "Dark Energy", or the actual vector Momentum Energy cmV= cP. This is The Quaternion Universe with scalar and vector energy!
