Pacemakers designed for long-term use commonly employ lithium-iodine batteries that are capable of supplying 0.42 A⋅h of charge.
a. How many coulombs of charge can such a battery supply?
b. If the typical current produced by the pacemaker is 5.6 μA, what is the expected lifetime of the device?

Answers

Answer 1

The movement of electrons is current. This battery will be capable of delivering 1,512 C of charge.

The flow of electron-deficient atoms, or electrons, is what is known as current. I is used to symbolise it. Moreover, one column of electrical charge is equal to one ampere, the SI unit of current.

Current, I₀ = 0.42A⋅h

current that the pacemaker generates , I₁ = 5.6μA = 5.6 x 10⁻⁶ A

A.) The relation, which may be used to calculate the number of coulombs the battery can produce,

Q= I x T

Q = 0.42 x 3600

Q = 1,512 C

Hence, this battery will be able to deliver 1,512 C of charge.

B.) As the charge was previously discussed using the same relationship,

Q= I xT

When we are aware of the current and charge the battery and pacemaker create,

1512 = 5.6 x [tex]10^{-6}[/tex] x t

t = 2.7 x [tex]10^{-4}[/tex] sec

As a result, the device should last 2.7 x [tex]10^{-4}[/tex] sec.

FILL IN THE BLANK. a ______ has three leads identified as base, collector, and emitter.

Answers

The emitter, collector, and base—or, in more recent switching applications, the source, drain, and gate—are the three electrical leads that commonly make up a transistor.

transistor: a semiconductor signal-generating, regulating, and amplifying device. Integrated circuits, or "microchips," which frequently have billions of these tiny components etched onto their glossy surfaces, use transistors as their active parts.

Transistors, which are present in practically every electronic component, have evolved into the brain cells of the information age. The ability of the semiconductor material to conduct electrical current, which in most applications moves between the emitter (or source) and collector (or drain), is influenced by an electrical signal supplied to the base (or gate). Similar to how a faucet valve is used to control the flow of water through a garden hose, a voltage source, such as a battery, drives the current, but the rate of current flow through the transistor at any one time is controlled by an input signal at the gate.

Nowadays, transistors are used in millions of components per integrated circuit in microprocessors and computer memory microchips, which include solid-state multimedia storage systems for electronic games, cameras, and MP3 players. Here, whether current may flow from the transistor's source to its drain is determined by the voltage applied to the gate electrode, which is typically a few volts or less.

name three criteria for a good location for an air cooled condensing unit?

Answers

An air-cooled condensing unit is an important component of an air conditioning system. The following are three criteria for a good location for an air-cooled condensing unit: Adequate Airflow,  Level Ground, and Protection from the Elements.

1. Adequate Airflow: An air-cooled condensing unit requires adequate airflow to function properly. The unit must be placed in an area where there is enough space for air to flow around it. This allows the unit to expel the heat it has absorbed from the indoor space. Therefore, the location should be free of any obstructions that can restrict the airflow, such as walls or vegetation.

2. Level Ground: The condensing unit should be installed on level ground. This is because the compressor and other components inside the unit are sensitive to vibrations, and they can become damaged if the unit is not level. A level surface also ensures that the refrigerant flows evenly through the system, which is important for optimal performance.

3. Protection from the Elements: The location of the condensing unit should provide protection from the elements. Exposure to harsh weather conditions can damage the unit and reduce its lifespan. Rain, snow, and direct sunlight can all cause problems, so it's best to install the unit in a protected area, such as under an overhang or in a shaded spot.
