(a) State ohms law.(b) Draw a circuit diagram for the verification of Ohms law.(c) The potential difference between the terminals of an electric heater is 60 V when it draws current of 4 A from the source. What current will the heater draw if the potential difference is increased to 120 V.

a) Ohm's law: At constant temperature current flowing through a conductor is directly proportional to potential difference between the terminals.
b) The figure is on NCERT science textbook (class 10) page no:204 figure 12.2
c) V=60V
I=4A
R=V/I=60V/4A=15Ω
I=V/R=120V/15V=8A
