Wire coild inside an electric toaster gets hot when a current flows through it the property of this wire to produce lots of heat from electricity is measured in?
The property of the wire to produce heat from electricity is measured in terms of its resistance to the flow of electric current, commonly expressed in Ohms (Ω). Specifically, the wire's ability to convert electrical energy into heat energy is quantified by its resistance value, as described by Ohm's Law (V = I * R), where V is voltage, I is current, and R is resistance.
Can you distinguish a metallic element from a nonmetal with dulong law?
Dulong's law, which relates the molar heat capacity of elements to their atomic mass, primarily applies to metallic elements. Metals typically exhibit higher molar heat capacities compared to nonmetals due to their structure and bonding. Nonmetals generally have lower molar heat capacities and different thermal properties. Thus, Dulong's law can help distinguish metals from nonmetals based on their heat capacity values in relation to their atomic masses.
How much resistance should be on a 5.0 kw heat strip?
Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
What happen if a 110 volt lamp connected on a low voltage?
If you had a 60 watt incandescent bulb it would draw about 1/2 amp. That means that the resistance of the bulb filament would be about 220 ohms. Now if you applied 12 volts DC across 220 ohms you would draw about .05 amps. This would not be enough to heat the filament and create any useful light. Remember Ohm's Law says Volts = Amps x Ohms.
What is the approximate atomic weight of pt by using the dulong and petit?
The Dulong and Petit law states that the molar heat capacity of a solid element is approximately 3R, where R is the gas constant. For platinum (Pt), this law can be used to estimate its atomic weight by measuring its specific heat capacity. Platinum has a specific heat of about 0.133 J/g·K, and using the Dulong and Petit approximation, the atomic weight of platinum can be estimated to be around 195.08 g/mol, which aligns closely with its known atomic weight.
Is ohms law heat and light?
No.
How do you calculate 1.67 ohms?
ohms law.
Why does a short circuit drain a battery?
You have to remember ohms law Voltage = amp * resistance. Using some basic algebra you can rewrite the equation as amps = voltage / resistance. Since a short circuit has relatively 0 ohms of resistance, this increases both the amps and resistance which uses more battery capacity,power, and creates more heat.
How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
How do you figure power lost as heat in electricity?
To calculate power lost as heat in electricity, you can use the formula P = I^2 * R, where P is the power lost in watts, I is the current in amps, and R is the resistance in ohms. This equation is based on Ohm's Law (P = V^2 / R) and Joule's Law (P = I^2 * R), which relate power, voltage, current, and resistance in an electrical circuit. By knowing the current and resistance in a circuit, you can determine the power lost as heat.
