Question

200j of heat is produced in one second from a resister of resistance 8ohm find the potential difference across the resister and it's power ​

Answer 1

Answer:

physics

Explanation:

Data:

H= 200j

t= 1sec

R=8 Ohms

v=?

P = ?

H= I ^ Rt

I ^ = H/ R.t

I^= 200/8×1

I^ = 25

I=/25

I = 5A

v= IR

= 5×8

= 40v

P= vI

=40×5

=200W

Answer 2

Answer:Given

H=200J, T=1second, R=8ohms,V=?,P=?

Formula,

H=ixixRxt

i=√H/RT

I=√200/8

I=√25

=5

I=5A

V=IR

=5x8

=40

V=40V

P=VXV/R

=40X40/8

=1600/8

P=200W
