Question: Does the same battery always deliver the same amount of flow to any circuit? Mention two observations of any circuits that you have seen in this lab to support your answer.
Yes
[3] Some people think that the flow of electricity is used up by the bulbs.
Does a battery always produce the same amount of current?
A battery maintains a nearly constant change in
electric potential across its terminals. When a complete circuit is connected from one terminal to the other, there is an electric current. Of course this current isn’t for “free”. … Yes, it is true that a current can be described as moving electrical charges.
Does the battery push through the same amount of current regardless of circuit type?
A battery has no such ability as push certain current
through a load regardless what a load wants and loads generally have no such ability as suck a certain current regardless what a battery offers. The current is a result, the found balance between the voltage and resistances in the circuit.
Can current flow from one battery to another?
During the discharge of a battery, the current in the circuit
flows from the positive to the negative electrode
. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
What determines how much current flows through a circuit?
The amount of current in a circuit depends on
the amount of voltage and the amount of resistance in the circuit to oppose current flow
. Just like voltage, resistance is a quantity relative between two points.
What are the 4 basic components of a circuit?
Every electric circuit, regardless of where it is or how large or small it is, has four basic parts:
an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch)
. Visualize what happens when you switch on a room light.
Can current flow without a source?
Voltage attempts to make a current flow, and current will flow if the circuit is complete. … It is possible to have voltage without current, but
current cannot flow without voltage
.
What is the direction of current inside a battery?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and
toward the negative terminal of the battery
.
What is the direction of current in a battery?
During the discharge of a battery, the current in the circuit flows
from the positive to the negative electrode
. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
Does current go from positive to negative?
Conventional Current assumes that current flows out of the positive terminal, through the circuit and into the
negative terminal
of the source. … In fact, it makes no difference which way current is flowing as long as it is used consistently. The direction of current flow does not affect what the current does.
How many amps does an average house use?
Most homes have an electrical service of
between 100 to 200 amps
. Amperage is a measurement of the volume of electricity flowing through wires, and this measurement can vary between 30 amps in very old homes that have not been updated to as much as 400 amps in a very large home with extensive electric heating systems.
What two factors affect the flow of a current?
- Potential Difference between ends (Voltage)
- Temperature.
- Material of wire.
- Length of wire.
- Area of Cross- section.
Why does current flow from negative to positive?
When an atom loses one or more electrons, it becomes a positive ion
because it now has more protons than electrons
. … The net result is a massive movement of electrons from the negative terminal of the battery to the positive terminal. This is how current flows in wires and cables and most electronic components.
What are the three types of circuit?
There are actually 5 main types of electrical circuits:
Close circuit, open circuit, short circuit, series circuit
What are the 3 requirements of a circuit?
- a conductive “path,” such as wire, or printed etches on a circuit board;
- a “source” of electrical power, such as a battery or household wall outlet, and,
- a “load” that needs electrical power to operate, such as a lamp.
What are the 3 basic electronic components?
- Basic electronic components: capacitors, resistors, diodes, transistors, etc.
- Power sources: Signal generators and DC power supplies.
- Measurement and analysis instruments: Cathode Ray Oscilloscope (CRO), multimeters, etc.
