Final answer is the total resistance in the circuit is 6
The Total current flowing in the circuit is 2.8 Amps
Explanation:
The total resistance is Calculated by
1/ R = 1/5 + 1/20 + 1/15 +1/20 + 1/10
1/R = ( 12 + 3 +4+3 +6) /60
1/R = 28/60 = 7/15
Therefore R = 15/7 Ohms
Voltage = 6
Total Current = V/R = 6/(15/7) = 6 x7 /15 = 42/15 = 14/5 = 2.8 Amps
