Open circuit and short circuit test?
Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
When a 12 volt battery is connected across an unkown resistance there is a current of 2.5m amphere in the circuit find the value of resistance of the resistor?
4.8 ohms
If one of the three lamps blows out when connected in series what happens to the current in the other two?
In a series circuit there is only one path for current to flow. The current will flow through each good lamp. If any lamp opens (blows), then the circuit is broken and current flow stops. The older strings of Christmas tree lights used to be connected in series and it was hard to fine the blown bulb. If there were two burnt out bulbs almost impossible to find.
How do you find the electromotive force if you only know the terminal voltage?
If the power source is not connected to a circuit, or the circuit is broken so no current flows, then the Terminal Voltage is the Electromotive force. Otherwise you need more information.
Wt is source current and sink current in a DC regulator?
The source current is that current which will leave the DC regulator and travel to the load circuit connected to it. The sink current is that current which may come from the load circuit and attempt to find a path through the ground through the regulator. Generally most regulators are designed to just source current to a load and are not setup to receive current back(sink it)
How 3 phase motors runs without neutral?
how does the current flow in a three phase circuit when neutral is not connected? A balanced three-phase 4-wire circuit - one with equal currents in all three live wires - has zero current flowing in the 4th wire, the neutral. Therefore the neutral wire can be removed, leaving just the three live wires. Instantaneously, the sum of the three currents is always zero in a balanced three-phase circuit. As an example, when the current reaches its peak in one wire, say 10 amps, the current in the other two wires is one half, 5 amps, in the opposite direction. Therefore the two wires take the return current for the first wire. This state of affairs happens continuously at every instant in the AC cycle, so three lives wires are all that is needed.
How do you find phase and neutral in the circuit?
Neutral will be closest to protective earth ground. In the US, neutral is white. we can check using tester ,when tester is connected to phase only lamp of the tester glows and when it is connected to the nuetral the lamp does not glow. another method is, connect the voltmeter to any one of the terminal and ground if the voltmeter shows 110v 0r 220v then it is phase and the other is nuetral.
How can I determine how to find an open neutral in an electrical circuit?
To find an open neutral in an electrical circuit, you can use a multimeter to test for continuity between the neutral wire and the ground wire. If there is no continuity, it indicates an open neutral. Additionally, you can visually inspect the wiring for any signs of damage or loose connections.
What is the net resistance of the circuit connected to the battery in the figure?
To find the net resistance of the circuit connected to the battery in the figure, you need to calculate the total resistance by adding up the individual resistances in the circuit.
In house wiring can the white wire have some current too?
Yes. The white wire (the "neutral") is the "return" for the hot. Recall that electric current had to "get to where it is used" and then has to "get back" to the outlet. (A complete circuit is necessary.) You need the black wire (the "hot" wire) to carry the current out and the white wire to carry the current back, and the currents should be equal. You don't want any current returning on the ground wire or "leaking to ground" from anywhere in the circuit. Another way to look at this is that the black and white wires form "rails" for the voltage. Anything hooked up is connected "across" the rails. It's connected from the black to the white - from one rail to the other. All the appliances in the house are connected in parallel across the black and white, or in parallel across those voltage rails. (That's why all appliances operate on the same voltage and why if one fails, it doesn't affect any of the others.)
Where is a voltmeter connected in a circuit?
Volt Meter is used to find the potential difference which is between the +ve or negative or between a Phase and Neutral etc. As it measure the potential difference, we need to connect in parallel which are tje extreme point of circuit starts and close, I mean completes.
How to find the neutral wire in an electrical circuit?
To find the neutral wire in an electrical circuit, you can use a voltage tester or a multimeter. Turn off the power to the circuit, then test each wire to see which one has a voltage reading close to zero. This wire is the neutral wire. Remember to always follow safety precautions when working with electricity.
