What is the value of internal impedance of ideal current source?
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
What is practical voltage source?
in case of ideal voltage source we consider the internal resistance to be zero.but in practical,every battery has some internal resistance then if you connect a load resistance across the terminals of that source,the net potential difference's across the voltage source will be a function of external resistance connects it won't give constant voltage across it's terminals.
A dc voltage source of 10V is in parallel with a current source of 5A and a resistance of 1 ohm what will be the current across the resistance?
use kvl or kcl
How can convert voltage source into current source?
Take the internal series resistance of the voltage source and make it the internal parallel resistance of the current source. Then compute using Ohm's law the current of the current source to be equal to the maximum current the original voltage source could supply a short circuit load. Note: the two sources are equivalent.
Does the ideal voltage source have an internal resistance of zero ohms?
yes
What is the current in a copper wire that has a resistance of 2 ohms and is connected to a 9-volt electrical source?
Current equals Voltage divided by Resistance. 9/2=4.5 amps.
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 will happen to the brightness of blub connected in series with a solenoid with a source of dc?
THE brightness would decrease as solenoid would have some resistance.
What is internal resistance?
it is a type of resistance which inbuilt in voltage source
Why internal resistance of an ideal voltage source is zero and an ideal current source is infinty?
Current source means current generator for a circuit. An ideal current source gives all current to the circuit, but practically a current source does n't give all current to the circuit, instead, a source resistor is connected in parallel to the current source to indicate the current drop.
Is air a source of resistance?
Yes, it is.
What is the value of internal impedance of ideal current source?
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
What resistance would produce a current of 25 ampers?
resistance does not produce currents . you need source (like voltage source , current source ,or , discharging capacitor) to generate current .
Does a voltage source have resistance?
Voltage source: is any source that voltage and amperage come from. Resistor: is any part of a circuit that consumes that energy!
What is practical voltage source?
in case of ideal voltage source we consider the internal resistance to be zero.but in practical,every battery has some internal resistance then if you connect a load resistance across the terminals of that source,the net potential difference's across the voltage source will be a function of external resistance connects it won't give constant voltage across it's terminals.
Why the resistance of a voltage source is infinity?
It isn't. See the answer to your question about a current source.
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
