Answer:

The resistance is 440 ohm and heat produced for 4 min is 26400 joules per second.

solution :

Resistance is 440 ohm, Heat produced is 26,400 J / s

Explanation:

STEP 1:

given,

power = 110W

voltage =220 V

Formulae;

P = (V ^ 2 / R)

STEP 2:

From the formulae we obtain,

11O = 220 ^ 2 / R

Therefore Resistance R = 220 ^ 2 / 110

=48400/110

=440 ohm.

STEP 3:

Heat produced =power *1 time

Power = 110W

Time =4 min

=48400/110

=440 ohm.

STEP 3:

Heat produced = owert time

Power =110 W

e = 4min

(1 min=60 sec)

=4*60

=240 )sec

STEP 4:

Heat produced =110*240

=26400 J/s

The resistance is 440 ohm and heat produced for 4 min is 26400 joules per second.

Answer:

P=V^2/R

110=220*220/R

R=220*220/110

=440ohm

E=P*t

=110*4*60=26400J
