Question

1. What is the current in each loop?

2. The 820 ohms resistor is really a combination of three resistors, one of which is 330 ohms the second of which is 100 ohms and the third unknown. What is the value of the third resistor, and how are they combined?

3. Where would you place an ammeter in each branch of the circuit to verify your calculations from part one?

What is the current in each loop? The 820 Ohm resistor is really a combination of three resistors, one of which is second of which is 100 Ohm, and die diird is unknown. What is the value of the

Explanation / Answer

loop 1:

10-100i1+5-15i1-150i-330i=0

15-580i-15i1=0--------1

loop 2:

10-100i+20-820i2+15-1500i2-150i-300i=0

45-550i-2320i2=0------2

solving 1 & 2:

-17850+1345600i2-8250i1=0--------3

loop 3:

15-1500i2+15i1-5+20=0

30+15i1-1500i2=0---------4

from 3 & 4:

current in each loop: 0.0083 A, 0.0267 A

2)

third resistor 590 ohm, connected in series

3)

before 100 ohm in first

before 800 ohm in second
