Question

resistance of a conductor in which 5 mA of current is flowing through 12 volt potential difference is
a)240ohm
b)2400ohm
c)24ohm
d) 24000ohm​

Answer 1

Answer:

b)2400ohm

where, i = current

v=voltage

R=resistance

Answer 2

Answer:

Resistance = 2400 ohm

Explanation:

Given that-

Current = 5 mA

$i = 5 \times 10^{-3}$ Amp

Voltage (V) = 12 volt

Resistance (R) =?

We know that-

Voltage = Current × Resistance

V = iR

$R = \dfrac{V}{i}$

  $= \dfrac{12}{5 \times10^{-3}}$

  $= \dfrac{12 \times1000}{5}$

         = 12 × 200

R = 2400 ohm

Resistance = 2400 ohm

Hence, option b is correct.
