Question

i need the answer for this question​

Answer 1

R=V/I
R=12/12×10^-3
. =1000

Answer 2

Question :-

when a 12V battery is connected across an unknown resistor, a current of 12mA flows in the circuit. Find the value of the resistor.

Answer:-

given :-

• V = 12V
• I = 12mA

__________________________

we know that,

1A = 1000mA

so,

12mA = 0.012A

__________________________

by ohm's law,

V = IR

or,

R = V/R

__________________________

R = 12/0.012

multiply numerator and denominator by 1000,

R = 12000/12

R = 1000

__________________________

Therefore, the value of resistor is 1000 ohm.
