Question

320J of heat is produced in 10s in 2 Ohm resistor. Find the amount current flowing through the resistor.

Answer 1

4 ampere
v=ir
v=w÷q
q=iT
v=2i
w/q=2i
w=2i×iT
i×i=w/2T
i×i=320/2T
i×i=160/10
i×i=16
i=4

Answer 2

Answer:

i=4

Explanation:

v=ir

v=w/q

q=it

v=2i

w/q=2i

w=2i×it

i×i=320/2t

i×i=160/10

i×i=16

i=4
