What is the power of a parallel circuit with a resistance of 1000 and a current of0.03 a?
I don't know what the parallel circuit has to do with it. You've onlygiven me a resistor and the current through it.When 0.03A of current passes through a 1,000Ω resistor, the resistordissipates energy at the rate of 0.9 watt.
What causes a resistor to heat up?
The current through a resistor or for that matter any conducting medium is caused by flow of electrons. These electrons do not flow like a stream through the resistor or conductor but undergo repeated collisions with the vibrating atoms of the resistor, transferring their kinetic energy to them. This in turn increases the vibrational energy of the atoms and manifest itself as heat in the resistor/ conductor. In turn this results in reduced drift velocity of the electrons resulting in reducing the current , thus acting as a Resistor.
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
Where do mechanical transfer energy?
they transfer energy through sound water and air.
What is the transfer of heat through the emptiness of space an energy called?
Convection is the transfer of energy through space.
Is an resistor an conductor or a insulator?
A resistor is a conductor that dissipates some of the electrical energy fromthe current flowing through it. The energy dissipated by the resistor is(current through it)2 x (resistance)

What do a resistor do in a circuit?
A resistor is a device that impedes or limits the flow of electrical current in a circuit. It converts the current's electrical energy into heat (thermal) energy. A resistor reduces the amount of energy in a circuit and pumps it out as a heat.

Why is a transfer useful in an amplifier?
Transfer means to allow through (science-transmit e.g a window and light energy. the light energy is transmitted through) and so if the energy wasnt allowed through there wouldnt be a current or circuit because the energy would be lost i the amplifier
How are power dissipated in a load or in a resistor?
Due to energy usage and/or the reduction in conductance (increase in resistance) in a given load or resistor, some electrical energy is lost through that component. As such, a proportional drop in current and voltage occurs.
Can you transfer energy through bluetooth?
No. You can not transfer energy through bluetooth.
What slows down current and converts electrical energy into other forms of energy?
That sounds like a resistor. However, please note that "slow down a current" is not a very accurate description of what happens. What the resistor does is take energy away from the current.
What are resistors?
A resistor is an electrical device that limits current in a circuit. It converts electrical energy into thermal energy (heat), and drops voltage. Conductors in an electrical circuit allow current to flow through them will little resistance. The medium in a resistor, the resistive material, is not a good conductor, and will "resist" the current that wants to flow through it. This is how it limits current in a circuit. A resistor is rated according to its resistance and it ability to dissipate heat. It will be rated in ohms of resistance and in watts. A one ohm resistor will allow one amp of current to flow through it when one volt is applied across it. It will generate one watt of thermal energy, which it will have to dissipate as heat.A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.
Why is it necessary to have a closed circut to have a complete transfer of energy?
Current can't pass through an open circuit .
Why do resistor voltage decrease while capacitor discharges?
The reason why resistor voltage decreases while a capacitor discharges is because the resistor acts like a source of electrical energy. As the capacitor discharges, it draws energy from the resistor, which causes the voltage across the resistor to decrease. This is because the capacitor is acting like a drain, and is taking energy out of the resistor, thus causing the voltage across the resistor to decrease. The resistor and capacitor work together in order to create a discharge circuit. This is done by connecting the capacitor to the resistor, and then to a voltage source. The voltage source supplies the energy to the resistor, and then the resistor transfers this energy to the capacitor. As the capacitor discharges, it takes energy from the resistor, which causes the voltage across the resistor to decrease. In order to understand this process better, it is important to understand the basics of Ohm's Law. Ohm's Law states that the voltage across a resistor is equal to the current through the resistor multiplied by the resistance. As the capacitor discharges, it takes energy from the resistor, which means that the current through the resistor decreases, and therefore the voltage across the resistor will also decrease.
