Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decreases

Hint— Describe the experiment using a circuit diagram. Give details showing that same potential difference exists across each resistance in a parallel circuit.

Electric cell

In metals with increase of temperature, the kernels start vibrating at faster rate and thus offer resistance to the ow of electrons. Hence, conductivity decreases. In case of semi-conductors, with...

This is because the overall cell reaction does not involve any ion in the solution whose concentration changes during its life time

A cell or a battery.

(d)  -1/4kx2. Explanation:-  The work done by the spring on both of the masses is equal to the potential energy stored in the spring. The potential energy stored in the spring =...

The expression for ‘r’ in terms of e, V and R is r = (ε/v - 1)R.

For potential drop, t = 30 min = 180 sec Vi = Vf + iR => 12 = 10 + 2i => i = 1 Amp m = Zit = (107.9)/(96500) x...
