Zener diodes attempt to keep terminal voltage constant. If the load is fairly small, a single zener diode can be used for this purpose. If the load is large enough that the zener cannot hold the voltage within desired margins, I suggest using the zener to control the base of a power transistor; the emitter or collector (depending on transistor type) will be used as the output to the load.

Safe working practices are systems of work that are carried out in a safe manner for any given task. Although most businesses use safe systems as a matter of course, it is best to record these and make sure they are communicated to your employees by giving them a copy of th recording during their training.

Depends upon the capacitance. The time of holding charge can analyse by transient analysis.

A: Assuming the same power output the switching type will be lighter in weight and less bulky.

The ampere-hour rating of series connected batteries is the same as that for one battery, so the ampere-hour rating of four 65 Ah batteries in series is still 65 Ah.

The reason for this is Kirchoff's current law - the signed sum of the currents entering a node is zero - or - the current at every point in a series circuit is the same.

The purpose of a voltmeter is to indicate the potential difference between two points in a circuit.When a voltmeter is connected across a circuit, it shunts the circuit. If the voltmeter has a low resistance,it will draw a substantial amount of current. This action lowers the effective resistance of the circuit andchanges the voltage reading.

Digital quantized information and analog is just information. Like the letter "i" on your screen is digital and made up of a few pixels= quantized. The letter "i" drawn on a piece of paper is not quantized = analog.

The maximum number of possible states in a circuit with 6 flip flops is 26 or 64.

hf

A ct is a step up transformer where as a pt is a step down transformer because both are used for measurement and protection purpose . current is stepped down if the secondary windings are more so we can obviously say thar ct is step up transformer

Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)

by using some of the converters we can swap the analog dash into digital

The total current in a transistor is the emitter current, which is the sum of the collector current and the base current. The ratio of collector current over base current, in linear mode, is beta-DC, or hFe. However, in order for linear mode to be true, the ratings of the transistor must not be exceeded, and the collector current must not be limited by the circuit. Note also that hFe is temperature dependent, and is expressed in the data sheet as a minimum, not an absolute value - it can vary from transistor to transistor.

The charge transferred in 25 minutes by a current of 500 mA is 750 coulombs.

Amperes is defined as coulombs per second, so 500 mA is 0.5 coulombs per second. 25 minutes is 1500 seconds, so the charge is 750 coulombs.
