What else can I help you with?
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?
Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
What would the results of voltage drop test be if the circuit is open?
voltage drop is zero bcz in open ckt current will be zero
What is the symbol for a open circuit?
When a circuit is in off condition then it is called an open circuit..
What is open circuit characteristic?
The terminal voltage is equal to the supply voltage and there is zero current.
What does the reading on a ammeter say when the switch is open?
An open switch in a circuit will stop all current flow so the ammeter should read zero amps.
Why zero sequence current cannot flow through a star connected machine unless the neutral is grounded?
If the neutral point is not earthed than the zero sequence current will not have any return path.It will be an open circuit for the zero sequence circuit.
What will an ammeter show if the circuit is broken?
Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
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
When the transformer is connected to the power source the secondary current is 0 what is the possible fault in the transformer?
A secondary current of 0 would suggest to me that the secondary circuit is open. A normally operating circuit with zero current flow would be very unusual. No load in secondary circuit. No secondary current can also be attributed to the primary power source open or an open primary winding.
Why short circuit and open circuit are equivalent appropriate?
In circuit equivalence, voltage and current sources are respectively equated to short and open ckt because of the very nature of them. A voltage source has zero internal resistance and current source has infinite internal resistance hence their equivalents:-)
What stops the current flowing in a circuit?
Current will cease when either or both the potential difference across the load is Zero or when the load, itself, is Infinite in resistance or impedance.
