Is diode an active or passive device?
An active device is a device that takes input energy to operate. The only energy a diode uses is from the signal applied to it (it has one input, one output, and no other terminals), so it is a passive device. To be an active device, a separate power source must be applied to it - such as the case for operation amplifiers, for example.
What are three things do electronic hardware devices in order to function?
A method for the CPU to communicate with the device, Software to instruct and control the device, and Electricity to power the device.
Assume a device draws 50ma of current and 150vdc across it what is its resistance?
Ohm's law: Voltage = Current times Resistance Solve: Resistance = Voltage divided by Current So, a device drawing 50ma with 150V has a resistance of 150 / 0.05, or 3000 ohms. p.s. Since power is volts times amps, that device is dissipating 7.5 watts.
Why TRIACS blow?
You exceed the power dissipation capability of the device and it burns up. Too much voltage across the terminals , too much current being passed through it, reverse voltage spikes can all cause the triac to "blow".
Is a microphone a instrument?
Yes, it is an instrument for recording. A microphone is a sensor device that converts mechanical pressure waves or sound in air into electrical voltage waves. Speaking into a microphone excites (moves) a diaphragm that is coupled to a device that creates an electrical voltage proportional to the produced sound pressure.
Can you use a 12v power adapter when device requires 6v?
No, twice the voltage applied to a device that only requires 6 volts will probably destroy the device. When a manufacturer of equipment states a required voltage for a device that is the voltage that must be used.
Is low voltage harmful to electronics?
No the low voltage is not harmful for all ever . if you applied low voltage than the output power of your device will low and you can also observe that the performance of your device will also reduce. it may also make the device inactive.
What is meant by rated voltage?
the voltage which is mainly applied to primary side of the transformer is called rated voltage.Answer'Rated voltage' is the nominal voltage at which an electrical device has been designed to operate.
What is peak detector?
a device which output voltage is almost the real peak valueof an applied signal
What will happen if you use phase to phase voltage for a single phase device?
If a single-phase device is connected to a phase-to-phase voltage, the device may get damaged due to the higher voltage applied. Single-phase devices are designed to operate at a lower voltage compared to phase-to-phase voltage levels typically found in three-phase systems. It is important to match the voltage ratings of the device with the supply voltage to prevent damage.
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.
What do you mean by offset adjustment in electronics?
Voltage or current Offset is the voltage or current seen at the outputeven when no input is applied. This happens due to various reasons such as imbalance in the device, asymmetry and many more. So, offset adjustment means, providing the required input externally, so that the output voltage and current are zero.
Why is it thatFET is called a voltage operated device?
since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain...so it is known as voltage controlled device.. for example..in a mosfet..the current from drain to source depends upon the width of the depletion layer..which in turn depends upon the voltage applied on the gate.. so that is the reason
How do you work thyristor?
The thyristor functions in such a way that when the anode voltage is greater than the cathode voltage , it is not triggered but only triggers when a gate signal is applied at the gate of the device.
What happens if you put dc on ac device?
the answer is Rectifier. it converts ac voltage into dc which can apply to the dc device
How transistors are classified on the basis of power?
There are two primary types of transistors classified on the basis of power: bipolar junction transistors (BJT) and field effect transistors (FET). Bipolar junction transistors are current-controlled devices, meaning that the amount of current flowing through the device is controlled by the voltage applied to the base electrode. The base-emitter voltage (VBE) and base-collector voltage (VBC) determine the amount of current flowing through the device. The current flowing through the device is given by the following equation: I = β * (VBE - VBC) Where β is the current gain of the transistor. Field effect transistors are voltage-controlled devices, meaning that the voltage applied to the gate electrode controls the amount of current flowing through the device. The voltage applied to the gate electrode determines the width of the conducting channel between the source and drain electrodes. The current flowing through the device is given by the following equation: I = μ * W * (VGS - VDS) Where μ is the mobility of the carriers in the channel, W is the width of the conducting channel, VGS is the voltage applied to the gate electrode, and VDS is the voltage applied to the drain electrode.
Is line voltage understood as any voltage?
Line voltage is understood as the voltage that the device or appliance needs to operate on. It is also referred to as the devices working voltage. Once the proper line voltage or working voltage is applied to the device it may be transformed to different voltages for different internal component circuits.
