1)🌟 Define these concepts: power source, conductor, load device. Give an example of each.
Power source: a power source is a source of power. Most commonly the type of power referred to is:
Load device: A unit load device (ULD) is a pallet or container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft.
2)🌟 List all the control and protection devices that you can think of and explain what they do.
One-way switch: Open or close the circuit when they are actuated.Power source: a power source is a source of power. Most commonly the type of power referred to is:
- Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time
- Electric power, the rate at which electrical energy is transferred by an electric circuit; usually produced by electric generators or batteries
Load device: A unit load device (ULD) is a pallet or container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft.
2)🌟 List all the control and protection devices that you can think of and explain what they do.
Push switch: Open or close the circuit, but only while we keep them pressed.
Two-way switch: Open and close one or more circuits. They can also open some circuits and close others ones simultaneously.
Limit switch: Functions as a switch toggles between two positions when it is operate by a lever.
Fuse: Protect the components of electric circuits from power surges.
3)🌟 Which materials are used to make an electric wire (inside and out)?
Wires are made of copper (inside) and of plastic casing (outside).
4) We know that the circuit in the figure below is equivalent circuit of two identical resistor connected in series, that the cell is 9V and that the current flowing through the circuits is 0.3mA.
a) Calculate the value of the equivalent resistor.
R= V / I > 9/0.3 = 30Ω
b) Calculate the value of the resistors in the initial circuit.
c) Draw the initial circuit.
