13. A resistor of 4 ohm is connected to a 1.5 V cell. What is the current in the cell? 
[0.375 amp]
14. When a 2 V cell is connected to a resistor the current in the resistor is 0.15 A. What is the resistance of the resistor ? 
[13.3 Q]
 

Dear Student

13. By ohm's law
V =IR
I =V/R = 1.5 /4  = 0.375 A

Please post different questions in different thread
