What does it mean to source current?
the source current is the current that flows from the power source.
If the resistance increases what will happen to voltage and current?
If you have a simple circuit. For eg: One voltage source and one resistor, then the voltage of the circuit will always remain the same, the current however will decrease following Ohms' Law V=I*R. If we have a current source instead of a voltage source, we are forcing the current to be a certain value so if we increase the resistor value the current will remain the same but the voltage will increase.
What is the maximum current that can be drawn from a voltage source?
The maximum current that can be drawn from a voltage source is dependent on the impedance of that source, the impedance of the connections to the source, and the energy available from that source.
Is zener diode an ideal current source?
A: An ideal current source can be defined as a short with immense current capabilities A zener has no such capabilities
Is current source available in any circuit?
The question is vague.A current source is the short form of constant current source.A voltage source, on the other hand, is the short form of constant voltage source.That being so, then no, a current source is not available in any circuit.
Why the Americium is used in smoke detectors?
In the smoke detector, the fast - moving alpha particles enable the air to conduct an electric current. As long as the electric current is flowing, the smoke detector is silent. The alarm is triggered when the flow of electric current is interrupted by smoke entering the detector.
What are the differences between proportional counter and gm counters in radiation monitoring?
The proportional counter is operating in linear mode, so the energy pulse measured by the detector is proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of both the activity (curies) and the energy (kEv) of the source. This detector is better at measuring the dose rate of the source. The Geiger-Muller detector, on the other hand, operates in avalanche mode, so the energy pulse measured by the detector is not proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of only the activity (curies) of the source. This detector is better at measuring the activity of the source, and can be more sensitive to lower energy particles, at the loss of discrimination of what those particles are.
How does tha current flows in the circuit?
Most people agree that current flows from the negative (cathode) terminal of the voltage source, through the load, and back to the positive (anode) terminal of the voltage source. This is because it is accepted that current is a flow of electrons. However, most analyses techniques use the convention that current flows from anode to cathode. It is simply a convention. So long as you are consistent in your usage of signs, you will be OK.
What happen when 2 different current source are connected in series connection with a resistance?
It is not recommended because one or other current source will be damaged by excessive voltage.
What does it mean to source current?
the source current is the current that flows from the power source.

What is the heat source for earth's convention currents?
The sun.
What ismean by current source?
A current source produces a constant current no matter the variation in voltage.
What does nuclear radiation have to do with how a smoke detector works?
A weak source of Americium-241 is found in smoke detectors. The Alpha particles, which ionise the air, are emitted from here. This causes the air to conduct electricity and a small current flows.
What are the benefits of owning a heat detector?
A heat detector is a good addition to the smoke alarm. It will help to detect a heat source that is growing in case the smoke alarm in the home is not functioning.
What is the simplest source of direct current?
Simple source of direct current are Batteries.
How hard is it to install a radar detector?
They are easy to install as they just need a power source and mounted.
