Solution to Exercise 4 on Page 58 Physics 11 Textbook

Problem Statement:

An accumulator has an electromotive force and internal resistance of ξ = 6V and r = 0.6 Ω, respectively. Using this accumulator, light a bulb labeled 6V - 3W. Calculate the current intensity flowing through the circuit and the potential difference between the two poles of the accumulator at that time.

Solution:

Solution to Exercise 5 on Page 58 Physics 11 Textbook

Problem Statement:

Two power sources have electromotive forces and internal resistances as follows:

ξ₁ = 4.5 V; r₁ = 3 Ω

ξ₂ = 3 V; r₂ = 2 Ω

Connect two sources into a closed circuit as shown in Diagram Figure 10.6. Calculate the current intensity flowing through the circuit and the potential difference UAB.

Solution:

Solution to Exercise 6 on Page 58 Physics 11 Textbook

Problem Statement:

In an electrical circuit with a diagram like Figure 10.7, two batteries have the same electromotive force ξ = 1.5 V and internal resistance r = 1 Ω

Two identical light bulbs with the same label on the bulb, 3V - 0.75 W. Assuming the resistance of the bulbs does not change with temperature.

a) Are the bulbs glowing normally? Why?

b) Calculate the efficiency of the power source.

c) Determine the potential difference between the two terminals of each battery.

d) If one light bulb is removed, what is the power consumption of the remaining bulb?
