when a 9v battery is conneted acros an unkown resistor there is a current of 3ma in the circuit.find the value of resistance of the resistor


abcd90: if current is 3 amphere then resistance is 3ohm and when current is 3 mega amphere then resistance will be 3/10×10×10×10×10×10

V=IR
R=V/I
R= 9/3*10^-3
= (9/3)*10^3
=3*10^3
= 3000 ohm
