Describe the Ohms law activity and draw the relevant circuit diagram

answered-by-expert Expert Answer

We know, 
Ohm's law states that
 
 V equals R cross times I w h e r e comma space V minus p o t e n t i a l space d i f f e r e n c e R minus space R e s i s tan c e space I minus space C u r r e n t
 
Ohm's law can be verified using following circuit diagram, 
 
 
Connect the circuit as shown in the diagram above.  
Change the value of potential difference (Voltage) across the conductor (here resistor) and note the respective value of current. 
Repeat the steps for 4 - 5 readings. 
After this, once you have 5 readings of current for its respective value of voltage you can calculate the value of 'R' using Ohm's law. 
After calculating you can see that value of R remains constant. 
Hence the Ohm's law is verified.
