An electric turntable 0.750 m in diameter is rotating, setting the stage for an exploration of physics, engineering, and practical applications. Dive into the world of turntables, where motion and precision intertwine.
The 0.750 m diameter electric turntable spins smoothly, powered by an electric motor. Speaking of electric motors, have you ever wondered an electric motor uses what type of current ? Anyway, back to our turntable: it rotates effortlessly, thanks to the reliable current flowing through its motor.
From its basic principles to its versatile uses, this article delves into the fascinating realm of electric turntables, providing insights into their construction, operation, and impact across various industries.
An electric turntable 0.750 m in diameter is rotating. The speed of the turntable is controlled by a variable resistor connected to an electric lamp of 100 ohms . As the resistance of the lamp is increased, the speed of the turntable decreases.
This is because the increased resistance reduces the current flow through the lamp, which in turn reduces the magnetic field strength of the lamp. The weaker magnetic field exerts a smaller torque on the turntable, causing it to slow down.
Conversely, decreasing the resistance of the lamp increases the current flow and the magnetic field strength, which increases the torque on the turntable and causes it to speed up.
Electric Turntable Overview: An Electric Turntable 0.750 M In Diameter Is Rotating
An electric turntable is a device that rotates a record or platter at a constant speed, allowing for the playback of audio recordings. It consists of a motor, a platter, and a tonearm with a cartridge and stylus. Turntables come in various types, including direct-drive, belt-drive, and idler-wheel drive, each with its own advantages and disadvantages.
Direct-drive turntables use a motor that is directly connected to the platter, providing instant start-up and accurate speed control. Belt-drive turntables use a belt to connect the motor to the platter, resulting in less vibration and noise. Idler-wheel drive turntables use a rubber wheel to drive the platter, providing a combination of torque and isolation from motor vibrations.
Yo, check it, an electric turntable 0.750 m in diameter is spinning like a champ. And guess what? An electric motor with two electromagnets is what’s making it happen. So, when that turntable’s gettin’ down, it’s all thanks to the magnetic action of that motor.
Electric Turntable in Motion
The rotation of an electric turntable is governed by the laws of physics. The angular velocity of the turntable, denoted by ω, is directly proportional to the frequency of the electrical current supplied to the motor. The relationship between ω and the frequency f is given by the formula:
ω = 2πf
Yo, check it! An electric turntable 0.750 m in diameter is rotating like a boss. But did you know that the power behind that spin comes from an electric motor? That’s right, an electric motor is used to convert electrical energy into mechanical energy, making that turntable spin like a champ.
So next time you’re dropping the needle on your favorite vinyl, give a shoutout to the electric motor that’s making it all happen.
where ω is in radians per second and f is in Hertz. The speed of rotation can be adjusted by changing the frequency of the current supplied to the motor.
An electric turntable 0.750 m in diameter is rotating, and an electric motor provides 0.5 W of mechanical power . That’s enough power to keep the turntable spinning at a constant speed, even if there’s a record on it.
Measuring Turntable Diameter
The diameter of a turntable is an important parameter that affects its performance. It can be measured using a ruler or a tape measure. To measure the diameter using a ruler, place the ruler across the platter at its widest point and measure the distance between the two edges.
An electric turntable 0.750 m in diameter is rotating at 33 1/3 rpm. A skater initially standing still on the turntable starts walking around the turntable’s edge at a speed of 1.50 m/s relative to the turntable. What is the angular velocity of the turntable after the skater is walking? (Neglect friction.)
An electric heater operating at 120 volts draws 10.0 A of current. What is the resistance of the heater?
Accurate diameter measurement is crucial for ensuring proper playback of records. A turntable with an incorrect diameter will cause the record to play at the wrong speed, resulting in distorted audio.
An electric turntable 0.750 m in diameter is rotating. Its rotational inertia is 12.5 kg⋅m2. An electric heater is rated at 2kw an electric heater is rated at 2kw . This means that it can generate 2,000 watts of heat, which is equivalent to 6,826.7 BTU/hr.
The turntable is rotating at a constant speed of 33 1/3 rpm. Its kinetic energy is 1,047 J.
Applications of Electric Turntables, An electric turntable 0.750 m in diameter is rotating
Electric turntables are used in a variety of applications, including:
- Playing vinyl records for entertainment
- Digitizing vinyl records for digital playback
- Mixing and scratching records for DJing
- Measuring the speed of rotating objects
