Question

40 ohms wire is cut into two equal parts the two parts are connected to a to 2volt source the find the amount of heat generated in one minute in the circuit ​

Answer 1

HEY MATE,

A WIRE OF 40 OHM RESISTANCE WHEN CUT INTO TWO PIECES.

SO RESISTANCE OF EACH WIRE WILL BE 20 OHM.

SO R = 20 OHM

V = 2 v

V = IR

V/R = I

2/20 = I

0.1A = I

SO, R = 20 OHM
TIME = 60 SEC.
I = 0.1A

HEAT = I2RT

= 0.1 X 0.1 X 20 X 60

= 12J

SO THE HEAT IS PRODUCED IS 12 JOULE

I HOPE THIS WILL HELP YOU...
