The figure shows a longitudinal section of a flower with a single ovule. The part labeled ’x’ represents the thalamus. The thalamus is the part of the flower that forms the receptacle which supports the rest of the floral organs.
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
