Question

Since you posted a question with multiple sub-parts. We will solve the first three sub-parts for you. To get the remaining sub-parts solved please repost the complete question and mention the sub-parts to be solved.

R,= 80 A 20 V R- 40 2 2) Measure and record the current in the ammeter. This is your experimental value. 3) Calculate the current using kirchhoff's loop law. This is your theoretical value. 4) Calculate the percent difference between two values. 5) Using voltmeter measure and record the potential difference between a and b. 6) Calculate the potential difference between a and b using known current, voltage and resistor values. 7) Find the percent difference between two values. 8) Using voltmeter measure the potential difference between each element in the circuit. (Make sure positive and negative leads of voltmeter connected in same pattern for each element) 9) Find the sum of potential differences across each element. 10) Check the validity of Kirchhoff's 2nd law ( sum of potential differences in any closed loop equal to zero).

Step 3 As the ammeter is connected in series of the circuit. The current which is flowing in the circuit is same as ammeter current. The current in the circuit can be calculated by the u sin g KVL Apply KVL 20 = I x R1 + IR2 + 8 12 = 0.1A I = R+R2 3) So the current in the ammeter is 0. 1 A 6) The potential difference between a and b Vab = -8 – 40 x 0.1 = -12 V 8 Potential difference between each element VRI = IRI = 8v VR2 = IR2 = 4V
