What is Ohms law?

Answer Posted / elumalai

According to Sir George Simon Ohm"when the current flows
through the conductor, the current is directly proportional
to potential difference between the two ends of the
conductor". ie
V=IR
Where R is the proportionality constant known as resistance
of the conductor. ie
R=$L/a
where $ is the resistivity of the material,
L is the length of the conductor,
a is the Area of cross section.

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
