Question

16. Three resistors are connected as shown in the diagram. Through the resistor 5 ohm, a current of 1 ampere is flowing. (i) What is the current through the other two resistors ? (ii) What is the p.d. across AB and across AC? (iii) What is the total resistance ?​

Answer 1

Answer:

effective resistance=[ 1/( {1/10 }+ {1/15}) ] +5

=6+5=11 ohm

current through 5 ohm 1 A

current through 10 ohm =10/25 ×1=0.4A

current through 15 ohm=15/25×1=0.6 A
