Which circuit should you use if you want to save money by using fewer parts?
Which circuit should you use (Parallel or Series) if you want to save money by using fewer parts? Why would this circuit be cheaper? Series because it uses less parts and electricity which costs less money.
Why do the rest of the bulbs stay lit if you break the connection at one bulb?
If one bulb goes out, no current flows in the circuit as the blown out bulb acts as an infinite resistance. (Two wires separated by air in between them). So other bulbs stop emitting light as well. If one bulb goes out, the other bulbs are unaffected as current still flows through the other bulbs.

How can you cause a fire?
Below are some of the most common causes of house fires, and some tips to take precautions.
- Cooking equipment.
- Heating.
- Smoking in bedrooms.
- Electrical equipment.
- Candles.
- Curious children.
- Faulty wiring.
- Barbeques.
How can you cause a fire in a circuit?
Here are the 5 most common causes of electrical fires. Electrical fire cause 1: Faulty outlets, appliances. Most electrical fires are caused by faulty electrical outlets and old, outdated appliances. Other fires are started by faults in appliance cords, receptacles and switches.
When electricity flows through wires and makes something work like a light bulb it is called a?
When electricity flows through wires and makes something work, like a light bulb, it is called a circuit. You will know you are successful when the bulb lights up and blue does (electrons) flow through. 1. Sketch your circuit below: 2.
Do electrons actually move in a wire?
Electrons do not move along a wire like cars on a highway. Each atom has electrons in it. If you put new electrons in a conductor, they will join atoms, and each atom will deliver an electron to the next atom.
How fast do electrons move in a wire?
The individual electron velocity in a metal wire is typically millions of kilometers per hour. In contrast, the drift velocity is typically only a few meters per hour while the signal velocity is a hundred million to a trillion kilometers per hour.
What causes electrons to move?
The “electrical pressure” due to the difference in voltage between the positive and negative terminals of a battery causes the charge (electrons) to move from the positive terminal to the negative terminal. Any path through which charges can move is called an electric circuit.
Do electrons move faster with higher voltage?
Yes, electron does goes faster in higher voltage. You can observe this phenomenon in Electron gun and cathode rays. or in Particle Accelerator. Voltage also increases current flow but that is not always the case.
Does a higher voltage mean a faster current?
Hence, the specific answer to your question is no. High voltages do not equal high currents. Voltage and current move inversely to each other. Higher voltage means lower current, and vice-versa.
Does higher voltage mean higher current?
The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.
What does the voltage do to the electrons?
Voltage, ( V ) is the potential energy of an electrical supply stored in the form of an electrical charge. Voltage can be thought of as the force that pushes electrons through a conductor and the greater the voltage the greater is its ability to “push” the electrons through a given circuit.
When resistance increases what happens to voltage?
This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease. Knowing any two of the three parameters allows us to calculate the third, unknown parameter.
