Using the image above, calculate the following:
1) Theoretical values of Av's across the resistors
2) Theoretical values of vabsolute and I (current) at points A,B,C, D, and E
3) Calculate the power of the battery and the power of all the resistors

Expert Solution

Step 1

Given in the circuit

Resistance in AB R₁ = 2.2 k $Ω$

Resistance in BC R₂ = 1.5 k $Ω$

Resistance in CD R₃ = 3.9 k $Ω$

Resistance in DE R₄ = 1.2 k $Ω$

EMF of battery is E = 3.10 volt

Step 2

Part 1)

All resistances are connected in series , so net resistance of the circuit is

$R = R_{1} + R_{2} + R_{3} + R_{4}$

R = (2.2 + 1.5 + 3.9 + 1.2) k $Ω$

R = 8.8 k $Ω$

Now current in the circuit is

$I = \frac{E}{R} I = \frac{3.10 v}{8.8 \times 10^{3} Ω} I = 0.3523 \times 10^{- 3} A I = 0.3523 m A$

All resistance are connected in series so the same current I is flowing in all resistances.

Now

Voltage drop across the R₁ is

V₁ = IR₁

V₁ = $(0.3523 \times 10^{- 3} A) (2.2 \times 10^{3} Ω)$

V₁ = 0.7751 volt

Voltage drop across the R₂ is

$V_{2} = I R_{2} V_{2} = (0.3523 \times 10^{- 3} A) (1.5 \times 10^{3} Ω) V_{2} = 0.5285 v o l t$

Voltage drop across R₃ is

$V_{3} = I R_{3} V_{3} = (0.3523 \times 10^{- 3} A) (3.9 \times 10^{3} Ω) V_{3} = 1.374 v o l t$

Voltage drop across R₄ is

$V_{4} = I R_{4} V_{4} = (0.3523 \times 10^{- 3} A) (1.2 \times 10^{3} Ω) V_{4} = 0.423 v o l t$
