What will be the resistance of 100w 210v lump? Resistance of the bulb: 625 Ω is the resistance of a bulb rated 100w ,250v. What is the resistance of the bulb marked as 20w 220v? Answer. putting values we get R= 242 ohm. What is the resistance of a bulb at 500w 220V? R=(220V)2100W=484Ω. What […]
What measurement represents volume?
What measurement represents volume? Volume is the measure of the amount of space occupied by an object. The standard SI unit of volume is defined by the base unit of length (Figure 3). The standard volume is a cubic meter (m3), a cube with an edge length of exactly one meter. Which choice best describes […]
How do you tell if a VOR is high or low?
What would happen if a bowling ball collided with a standing pin?
What would happen if a bowling ball collided with a standing pin? When the bowling ball collides with the pins, the momentum the ball loses is equal to the momentum the pins gain. An object’s inertia resists changes its motion. The momentum and force of a rolling ball is greater than that of the pins. […]
What is the most important intermolecular force in nf3?
What is the most important intermolecular force in nf3? This makes the structure of nitrogen trifluoride asymmetrical. Thus, it is a polar molecule. For polar molecules, the type of intermolecular force of attraction that dominates is dipole-dipole force. What is the strongest intermolecular attractive force in SiH4? The intermolecular forces exists among SiH4 molecules is […]

At what temperature does fusion welding takes place?
At what temperature does fusion welding takes place? 900°C Is welding permanent or temporary? Welding is a permanent joint and therefore it is not possible to dismantle the welded parts without partially destroying them. Riveting joint is another permanent joint; while fasteners, cotter joint, knuckle joint, etc. are temporary joints. What are permanent and temporary […]
Why are diodes important?
Why are diodes important? Conducting an electric current in one direction Despite being nothing more than a simple two-pin semiconductor devices, diodes are vital to modern electronics. Some of their most common applications include turning AC to DC, isolating signals from a supply, and mixing signals. What are the applications of diodes? The application areas […]
What is tolerance in a resistor?
What is tolerance in a resistor? The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value. What are […]
Who used a compound microscope to see Chambers?
Who used a compound microscope to see Chambers? Robert Hooke What details can Electron microscopes reveal? As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. What type […]
