Question

3 resistor of 5 ohms 10 ohms 15 ohms are connected to battery 30V ammeter and voltmeter are connected in circuit draw a circuit diagram to connected all device in proper order what is current and potential different across 10 ohms resistance

Answer 1

there are two possible cases 

1)series 


  if it is connected in series than resistance is 30  ohm

 so current is 1 A

 and pd bw than volts is 
 
 v= ir
 pd bw 10 ohm resistor is
 30 - 5 = 25 
 25 - 10 = 10 v
