Question

how much charge flows through a 250v -1000w heaterin 2 minutes.​

Answer 1

We know that,

R= V/I

R= 250/5

R=50 ohms.

Now,

Heat= I²Rt

Heat= 5*5*50*10*60

Heat= 7,50,000 Joules

Answer 2

Answer:

480 Coulomb

Explanation:

P=1000 W

V=250 V

Time= 2 mins = 120 sec

We know,

P=VI

=)I= P/V

=)I= 1000/250

=)I= 4 A

We know,

I = Q /T

=)Q= I×T

=)Q = 4×120

=)Q= 480 Coulomb
