Question

1) State the formula showing how the current I in a conductor varies when the potential difference V applied across it is increased stepwise.

2) When a potential difference of 1.2volt is applied across a conductor, the current
flowing In it is, 0.25 ampere. Calculate the resistance of conductor.




Please answer me ,...........

Answer 1

Answer:

the formula is v=ldi/dt

Answer 2

Answer:

1) V=IR

2) R= 4.8 ohm

Explanation:

1) As potential difference of a wire is diresctly proportional to the current flowing through it

2) V = I÷R

R=V÷I

R = 1.2÷ 0.25

R= 4.8
