Three resistors, with substances 250\(\Omega\), 500\(\Omega\) and 1k\(\Omega\) are connected in series. A 6V battery is connected to either end of the combination. Calculate the pot3ential difference between the end of the 250\(\Omega\) resistor.

  • 0.20V
  • 0.86V checkmark
  • 1.71V
  • 3.43V

The correct answer is: B

Explanation

Using voltage - divider method

v1 = \(\frac{(R_1)}{R_T}\)VT

= \(\frac{250}{1750}\) x \(\frac{6}{1}\)

= 0.86V
