If three resistors of 6ohm,9ohm and 21ohm are connected in series to a 12V battery, find the total resistance of the circuit, find the current flowing through the circuit, find the potential difference across the 21ohm resister

In seri
  • -1
In series total resistance Req = 9 +21+6 =36 ohm now current V=IR so 12 = I ?36 so I is 1/3 ampere now potential across 21ohm is V = 1/3 ? 21= 7volt

and v=12v
then I=v/R
