Why do materials like living cells heat up when electric current passes through them?
Living cells heat up when electric current passes through them due to the resistance of the cell's membrane, as well as the resistance of the internal cellular structures and ions. This resistance causes energy to be dissipated in the form of heat, leading to an increase in temperature.
Does A filment in a bulb have low resistance?
Filaments in bulbs typically have high resistance, which allows them to generate light and heat energy efficiently when electricity passes through them. The high resistance causes the filament to heat up and emit light.
Does the volume increase in each turbine stage?
The volume increases in each turbine stage as the expanding steam passes through the turbine blades. This expansion of steam causes an increase in volume and a corresponding decrease in pressure and temperature.
When an electric current passes through water it causes the water to start to combust?
no, when an eletric current passes through water, it causes the water to start to decompose into hydrogen and oxygen
What passes through the internal acoustic meatus?
The facial nerve and vestibulocochlear nerve pass through the internal acoustic meatus, which is a small bony canal located in the skull.
Why is the internal resistance of a voltage source made to be low?
When a voltage source, such as a battery or a generator, is on open circuit -in other words, when it is not supplying a load- the voltage appearing across its terminals is called its 'open circuit voltage' and corresponds numerically to its electromotive force.However, when the voltage source supplies current to a load, that current also passes through the voltage source itself. This causes an internal voltage drop, which is the product of this current and the voltage source's internal resistance. This voltage drop acts in the opposite direction to the electromotive force and reduces the source's terminal voltage. This internal voltage drop will increase, of course, if either the load current increases or the internal resistance increases.So, in order to keep that the source's internal voltage drop is as low as possible, its internal resistance must be as low as possible. In the case of a battery, the internal resistance is due to the ionic resistance of the electrolyte/plates, whereas in a generator it is due to the resistance of the windings.
Why do materials like living cells heat up when electric current passes through them?
Living cells heat up when electric current passes through them due to the resistance of the cell's membrane, as well as the resistance of the internal cellular structures and ions. This resistance causes energy to be dissipated in the form of heat, leading to an increase in temperature.
Why does a resistor get hot when electricity passes through it?
A resistor gets hot when electricity passes through it because the resistance in the resistor causes some of the electrical energy to be converted into heat energy. This heat energy is dissipated as the resistor resists the flow of electricity, leading to an increase in temperature.
When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
When you jump your car it want start cable get hot?
Electricity passes through the cable. As it passes through the cable, the electricity will encounter resistance. This is what causes an electrical cable to heat up.
Why does the current loose some of the energy when it passes through a bulb?
When current passes through a bulb, it encounters resistance in the filament of the bulb. This resistance causes some of the electrical energy to be converted into heat and light, resulting in a loss of energy in the form of heat radiation.
Why does the filament become hot?
The filament becomes hot when electricity passes through it, due to resistance in the wire. This resistance causes the filament to heat up and emit light in an incandescent bulb.
Does A filment in a bulb have low resistance?
Filaments in bulbs typically have high resistance, which allows them to generate light and heat energy efficiently when electricity passes through them. The high resistance causes the filament to heat up and emit light.
How can expansion take place when steam pass through a nozzle?
When steam passes through a nozzle, it undergoes adiabatic expansion due to the decrease in pressure. This expansion causes the steam to increase in velocity as it exits the nozzle, converting some of its internal energy into kinetic energy. The increase in velocity results in a decrease in pressure and an increase in velocity, which can be harnessed in devices such as turbines.
How can electricity turned into heat?
Electricity can be turned into heat through resistance heating. This occurs when an electric current passes through a material with resistance, such as a heating element or coil. The resistance in the material causes the electric energy to be converted into heat energy, which warms up the material and its surroundings.
Why filament gets heated?
Filament gets heated when an electric current passes through it, causing resistance in the filament wire. The resistance converts electrical energy into heat energy, which then causes the filament to reach high temperatures and emit light.
Why shunt resistance is used ammeter?
A shunt resistance is a low resistance connected parallel to the galvanometer so that a large portion of current passes through the low resistance and a small fraction of current passes through the galvanometer this saves the galvanometer from damage
