3 RESISTORS 2OHM,4OHM&5OHM ARE IN PARALLEL .IF THE COMBINATION IS CONNECTED TO BATTERY OF EMF 20V &NEGLIGIBLE INTERNAL RESISTANCE ,FIND THE CURRENT THROUGH EACH RESISTOR ,&THE TOTAL CURRENT DRAWN FROM THE BATTERY
Total resistance = 1/20 + 1/40 + 1/50 = 10.52 ohm
Total current drawn drawn , I = V/R = 20/10.52 =1. 9 A
Current through 20 ohms , I = 20/ 20 = 1 A
Current through 40 ohms , I = 20 / 40 = .5A
Current through 50 ohms, I= 20/50 = .4A
