What is the unit to describe the amount of electrical current passing through a ponit?
The unit to describe the amount of electrical current passing through a point is the ampere (A).
How is energy transformed in an electric lamp?
In an electric lamp, electrical energy is transformed into light energy and heat energy. When the lamp is turned on, the electrical current flows through the bulb's filament, causing it to heat up and emit light. Some of the electrical energy is also transformed into heat energy due to resistance in the filament.
What energy is transformed in a hot plate?
Electrical energy is transformed into thermal energy in a hot plate. The electrical current flows through the heating element, which generates heat through resistance, raising the temperature of the hot plate surface.
How does the battery in a torch work?
A torch, or flashlight, typically uses a battery to power the lightbulb. When the battery is inserted into the torch, it completes a circuit allowing the current to flow from the battery to the lightbulb, which then emits light. The chemicals inside the battery convert chemical energy into electrical energy, powering the lightbulb.
What is an example of kenetic energy being transformed to electrical energy?
An example of kinetic energy being transformed into electrical energy is when a wind turbine is in motion due to wind. The kinetic energy of the moving blades is converted into electrical energy through a generator attached to the turbine, producing electricity.

What type of energy do the circuit the batteries in the circuit have?
Batteries have chemical energy stored inside them. Of course, when they provide a current, this chemical energy is transformed (in part) into electrical energy.
How does a flaslight work?
A flashlight works by converting electrical energy from batteries into light energy through a bulb or light-emitting diode (LED). When the switch is turned on, the circuit is completed, and the electrical current flows through the bulb or LED, causing it to emit light.
Why is there zero current when a lightbulb burns out?
because there is no voltage and resistance?
When electrical current flows through the metal filament of a light bulbelectrical energy is coverted to?
When electrical current flows through the metal filament of a light bulb, electrical energy is converted to heat and light energy. The filament heats up due to the resistance it provides, emitting light as it reaches high temperatures.
What energy transformation takes place in a flashlight?
Battery (chemical energy) goes to the wires (electrical energy) which goes to the light bulb (thermal and electromagnetic energy. In the bulb of a traditional flashlight, electric current energy is transformed to heat and then partially to light, when the temperature of the filament in the bulb is sufficient. In an LED type flashlight, little heat is produced and more of the electrical current energy is transformed into light.
What term is used to describe memory that losses its data when the electrical current is turned off or interrupted?
Volatile.
What type of energy does a generator change to electricity?
A generator converts mechanical energy into electrical energy. By utilizing a magnet and a conductor to induce a flow of electrons, the mechanical energy is transformed into a usable electrical current.
