What else can I help you with?
Sparking occur when a load is switched off?
Caused by a voltage spike to do with collapsing magnetic fields in a load. A suppresor fitted across the terminals should stop it.
When A voltage sourcehaving a source impedance Z R jX can deliver maximum Average power to a load impedance Z?
the impedence should be complex conjugate of an equivalent impedence of the network when viewed from the terminals of the load. i.e; Z=R-jx
What is inherent voltage regulation of an onload tap changer for power transformer?
depending on the amount of the load of transformer as well as the power factor of it, there is a transformer specific voltage drop at its terminals, due to the internal impedances. The on-load tap changer can / will be used to compensate this voltage drop or rise.
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
What are input impedance in a load cell?
The resistance measured across the excitation terminals of the load cell, when the output terminals are open.
What function is performed by battery terminals?
The function of battery terminals is to connect a load or charger to a cell battery. Battery terminals are necessary and common in a lot of batteries.
When connecting 4 way switches care must be taken to connect the travelers to the?
Proper Pair of Terminals
How do you connect a main switch?
The line supply connects to the top terminals of the switch and the load connects to the bottom terminals of the switch.
What are the terminals on a solid state relay called?
The terminals on a solid state relay are typically called input terminals and output terminals. The input terminals are used to connect the control signal that activates the relay, while the output terminals are used to connect the load that is being switched on or off by the relay.
What is terminal voltage?
Terminal voltage is the voltage gotten at the terminals of the load in any system.
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
How to wire multiple GFCI outlets in a circuit?
To wire multiple GFCI outlets in a circuit, connect the line and load terminals of each outlet in parallel. The line terminals receive power from the source, while the load terminals provide power to downstream outlets. Make sure to follow the manufacturer's instructions and consult a professional electrician if needed.
Sparking occur when a load is switched off?
Caused by a voltage spike to do with collapsing magnetic fields in a load. A suppresor fitted across the terminals should stop it.
Why voltage measured at terminals of battery to which load is connected is always lower than open circuit voltage?
Real-world batteries do not have zero internal resistance. When one connects a load (resistance) to a battery, current begins to flow and the open-circuit potential is divided between the battery's internal resistance and the resistance of the load. Thus, one will measure a lower voltage at the battery terminals when a load is connected, compared to no-load conditions.
How do you wire a GFCI outlet?
To wire a GFCI outlet, first turn off the power to the circuit. Then, connect the line wires to the line terminals and the load wires to the load terminals. Make sure to follow the manufacturer's instructions and use a voltage tester to ensure the power is off before starting.
Why no load current is 5 percent of full load current in motor?
As the no load current is the current due to core losses of the motor which is very small .in no load terminals are open circuited no current flows through it, a small current flows which is due to core
