Can a series circuit have one electrical device?
No. You can have multiple devices on a series circuit. How about a low voltage Christmas tree light set. There you may have 15 or 20 lamps in series.
How does the low-voltage circuit controls the power to the high-voltage circuit?
Through a relay or some other kind of high voltage switching device.
Do you unplug before measuring resistance?
Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.
Transistor is a linear or non linear circuit element?
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
What type of devices would a voltage converter be used for?
Any type of device that would need to be converted from AC to DC power would use a voltage converter. Devices such as televisions, monitors, and other electronic devices could use a voltage converter.
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
Advantages of parallel circuit?
A parallel circuit can run several devices using the full voltage of the supply, varying the current to the need of each device. If one device fails, the others will continue running normally. If the device shorts, the other devices will receive no voltage, preventing overload damage.A series circuit divides the supply voltage among the devices with a consistent current. If one device fails, all other devices in the circuit will either fail to receive voltage or receive too much voltage and become damaged in the case of a short.An advantage of parallel circuits is increasing the power rating of the circuit and reducing the resistance.
How is a series circuit different from parallel circuit?
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
What device uses the voltage in an electrical current?
A voltage, or potential difference, is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.
Can a series circuit have one electrical device?
No. You can have multiple devices on a series circuit. How about a low voltage Christmas tree light set. There you may have 15 or 20 lamps in series.
What would be the most effective method to test a broken circuit?
Do a voltage test. Start at one end of the circuit and progress along device by device. If there is voltage on the down stream side of the device move on to the next. If there is no voltage on the down stream side of the device then go up stream of the device. If you have voltage there then the current device that you are at is the problem causing an open or broken circuit.
What is needed to calculate the voltage across a device?
you calculate a voltage circuit by taking it apart and findng the circuit and calculate the voltage and then resible it.
What type of electrical circuit is used least in industry and the home?
The most common of all circuits used in industry and around the home is the parallel circuit. In industry all MCC controls are in parallel with the supply distribution and around the home all lighting circuits are in parallel with the supply distribution panel.
What type of a device is used to increase or decrease the voltage in an electric circuit?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to transformers to provide customers with a regulated voltage at the desired voltage.
How does the low-voltage circuit controls the power to the high-voltage circuit?
Through a relay or some other kind of high voltage switching device.
What is difference between stabilizer and voltage regulator?
A voltage regulator is a circuit or device designed to deliver a constant voltage at its output regardless of changes in load current.A voltage stabilizer is a circuit or device designed to deliver a constant voltage at its output regardless of changes in incoming voltage.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
