Question

How much current flows through a 4kohm resistor when a potential difference of 2v is applied across its ends

Answer 1

Resistance ( r )= 4 kilo ohms = 4000 ohms

Potential difference ( v )= 2v

Current (i)= v/r

= 2 / 4000

= 0.0005 A

Answer 2

Answer:

0.0005

Explanation:

we know

V= 2v

R= 4000 ohms

I= V/R

I=2/4000

I=0.0005
