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 Share with your friends Share 1 Krishna answered this In seri -1 View Full Answer Krishna answered this 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 0 Brijesh Koley answered this 6+9+21=36ohm=R and v=12v then I=v/R I=12/36=1/3 2
