When a parallel LC circuit is tuned to resonance will the current be at a maximum or a minimum?
Inside the circuit loop between the inductor and capacitor the current will be at maximum. Outside the circuit the current through the LC tank circuit will be at minimum. It depends on where you are measuring it.
Why do the resistance is zero in case of short circuit?
The current is 0. Current is the unit of flow of electrons in a circuit, and in an open circuit, electrons cannot flow. Therefore there is 0 current. Another way to look at it is that I = V / R, where I = Amps (current), V = voltage, and R = resistance (impedance). In an open circuit, the impedance is infinite, and by using our math skills, we know that X (or V in our case) divided by infinity, is 0. I = V / Infinity = 0
What is Minimum diode Bypass current?
It depends of your panel ratings. usualy, a panel short-circuited has a maximum current, you can base the value on that. But if you are doing an array of panels, you have to pai attention to the parallel connection, once that multiplies the current across the circuit. in this case you have to use diodes that support the current of the array.
Minimum proper base emitter voltage at any instant?
The base-emitter voltage of a BJT is dependent on temperature and current. The minimum voltage ranges from 0.6V to 0.7V. Anything less, and the transistor goes into cutoff. As far as "proper voltage" is concerned, it is more correct to say "proper current", because that is the basis for the BJT - it is a current amplifier, not a voltage amplifier. The proper current depends on the particular biasing design of the circuit at hand.
Why does series rlc circuit provides voltage magnification at resonance?
IN A SERIES RLC CIRCUIT XL=XC.THEREFORE, IMPEDANCE Z IS MINIMUM AND Z=R.SINCE THE IMPEDANCE IS MINIMUM,CURRENT IN THE CIRCUIT WILL BE MAXIMUM. XL=XC MULTIPLYING BY MAX. CURRENT Io (AT RESONANCE) ON BOTH SIDES, WE GET, IoXL=IoXC I.E. Vlo=Vlc(POTENTIAL DIFFERENCE ACROSS INDUCTANCE IS EQUAL TO THE POTENTIAL DIFFERENCE ACROSS CAPACITANCE AND BEING EQUAL AND OPPOSITE THEY CANCEL EACH OTHER.)SINCE Io IS MAXIMUM,Vlo AND Vco WILL ALSO BE MAXIMUM.THUS,VOLTAGE MAGNIFICATION TAKES PLACE DURING RESONANCE.HENCE,IT IS ALSO REFERRED TO AS VOLTAGE MAGNIFICATION CIRCUIT.

When the circuit is said to be in resonance?
For a particular frequency if the current or the voltage of the circuit is Maximum or Minimum then that circuit is said to be in resonance .
Resonance in an L-C-R AC Series circuit experiment?
At resonant frequency, current in the circuit is maximum.Impedence is minimum.

What is the minimum value of current to trip the Earth leakage circuit breaker?
30 m amp
Will the current of circuit change on changing the ammeter resistance?
The accuracy of ammeter changes as the resistance is increased or decreased.AnswerThe simple answer is yes, it will change. However, whether it will be a perceptible change is another question. Ammeters are designed to cause the minimum change to the actual circuit current when they are inserted into a circuit.

What minimum level of a stimiulus required to activate a neuron?

What is the formula to find the mAh you need to run a circuit a certain amount of hours?
(mA of current the circuit draws from the battery when it's running) multiplied by (number of hours you want the circuit to operate from the battery) is equal to the absolute minimum mAh rating the battery must have.
How latching current is different from holding current?
Latching current is the minimum amount of current required to maintain the thyristor in on-state immediately after a thyristor is turned on..and Holding current is a minimum current that is required to maintain the thyristor in on-state not allowing it to turn off.Alternative AnswerIf you are referring to a relay or contactor, when the relay is de-energised, there is a break in the magnetic circuit, so the magnetic circuit has an airgap which makes it have a high reluctance. When the relay is energised, the magnetic circuit causes the armature to close, removing the airgap and reducing the value of reluctance. So, when you first energise the relay, there must be a greater magnetomotive to overcome the higher reluctance. When the relay is closed, a lower magnetomotive force will be sufficient to overcome the lower reluctance and maintain the relay closed.
What parts to circuits have to contain?
The absolute minimum for a circuit is continuity. Without this it is not yet a circuit.
What is shunt source?
The circuit is designed so that at maximum load current the shunt regulator draws virtually no current and at minimum load current, the shunt voltage regulator passes the full current. As a result, it can be seen that shunt regulators are inefficient because maximum current is drawn from the source regardless of the load current, i.e. even when there is no load current.
