Question

A capacitor is made by two parallel plates with area of each being A and distances between them as d. This is placed in an electrolyte with resistivity ⍴ and constant horizontal velocity v. The entire system is placed in a uniform magnetic field of induction β at 30o angle from the plate. The material between the places has an external resistance of R.

Calculate the amount of power generated in that resistance?

If the velocity of the electrolyte is doubled, at what value of R will the power be the highest?

At its highest power, the current flowing through the electrolyte is 5A. Calculate the potential difference at this point.

Removing the electrolyte, what type of capacitor is this?​

Answer 1

Answer:

Red and Rose entered into a partnership on the following terms on 1 Jan 15

(a) Red and Rose are to contribute capital of RS 1, 00,000 and 60,000 respectively

(b) Profits and losses are to be shared in the ratio 3:2

(C) Interest on capital at 5% p.a and on drawings @2% p.a

(d) Red is to get a salary of RS 1, 000 per month

(e) Rose is to get commission at 2% on the net profit of the firm before charging any of the above.

On 31st December 2015, their trading profits before about terms was RS.1,20,000. During the year, Red has written Rs.2,000 and rose

RS.1,000 on which interest to be charged for the whole year
