Question

Let the resistance of an electrical component remains constant while the potential difference across the two ends of the component decreases to half of its former value. What change will occur in the current through it?
​

Answer 1

According to Ohm’s law

V = IR

⇒ I=V/R ... (1)

Now Potential difference is decreased to half

∴ New potential difference Vʹ=V/2

Resistance remains constant

So the new current Iʹ = Vʹ/R

= (V/2)/R

= (1/2) (V/R)

= (1/2) I = I/2

Therefore, the amount of current flowing through the electrical component is reduced by half.

Answer 2

hey friend your answer

the amount of current flowing through the conductor will be half of the previous.
