What is the function of reference voltage?

A: Analogue and digital converters need a reference to weight the input related to the value of the reference. Other applications includes comparator switching and instrumentation


What is the supply for a diode?

The diode voltage drop is 0.7 volts, so you need that much to turn it on. Current is controlled by a resistor in series.


How much resistance is in the circuit if it uses a current of 0.01 A?

There is insufficient information in the question to properly answer it. You need to specify, also, the voltage, in order to determine resistance from current. Please restate the question. Ohm's Law: Resistance = voltage divided by current.


What is PIV.Why PIV of a semiconductor diode is important?

peak inverse voltage... piv of semiconductor is impoetant bcz we need to know after a peak voltage the diode get breakdown or damaged... so we need to know the peak voltage. piv is a point which withstands the maximum reverse biased voltage. after which the diode get damaged.


Four 50 ohms are connected in series calculate the current in the circuit?

The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.The series resistance is 4 x 50 = 200 Ohms.

Why PT Burden is always higher than CT Burden?

PTs are high voltage, low current transformers and so need a relatively high impedance (or burden) load to function accurately. CTs are high current, low voltage (if not open circuited!) transformers and so need a very low impedance load to function accurately.


What happens to the charge if you double the voltage across a capacitor?

In order to double the voltage across a capacitor, you need to stuff twice as much charge into it.

To purchase a Transformer are given input voltage output voltage and wattage sufficient?

How much does it cost? Will it fit in the space provided? Is cooling for it provided? When can it be delivered? Does it need provision for tapping for minor voltage changes? Does it need provision for remote monitoring? Voltage variation with load. Conformance with applicable standards. Frequency. A TRANSFORMER IS A PASSIVE DEVICE SO YES THE INPUT VOLTAGE IS NECCESSARY FREQUENCY OF OPERATION THE KVA OUTPUT IS ALL THAT YOU NEED.
