Is current is the rate of electrical flow in a circuit and that votage is the opposition of current flow?

'Electricity' is not a quantity; it's the name of a subject area or topic (just like 'chemistry'). So 'current' describes a flow of charge (not 'electricity'), expressed in amperes. 'Voltage' (potential difference) is responsible for 'driving' current, expressed in volts. 'Resistance' is the circuit's opposition to current, expressed in ohms.

What is rectifier and what is its use?
rectifier, it is a n electrical device that converts ths high votage carrying AC to low voltage carrying DC
What votage will cause an 8 amp current to flow through a 24 ohm resister?
Ohm's law: Voltage equals current times resistance. 8 amperes times 24 ohms equals 192 volts.
How does changing resistance affect voltage and current?
current change with resistance as, anything which opposes flow of current is called resistor is circuit, now we use battery to give potential across the circuit, potential just ensure the continuous flow of charge from higher to lower potential (water flows from high PE to low PE), while resistance opposes the flow of charge and thereby effecting the value of current, it's practically found that more is the resistance, less is the current flowing through resistance, this is indirectly observed from ohm law V=IR.
What is votage?
voltage is the amount of energy an electron carries
What is common to both thevenin and norton theorem?
To solve any D.C. circuit by using Thevenin Theorem,First of all load resistance RL is disconnected from the circuit and open circuit voltage across the circuit is calculated (known as Thevenin equivalent voltage)Secondly, the battery is removed by leaving behind its internal resistance. Now we calculate equivqlent resistance of the circuit ( called Thevenin equivalent resistance).Now we connect Thevenin Voltage in series with Equivalent resistance of the circuit and now connect load resistance across this circuit to calculate current flowing through the load resistance.Whereas in the case of using Norton theorem, we again remove the load resistance if any, and then short circuit these open terminals and calculate short circuit current Isc.Second step is same as in Thevenin theorem i.e. remove all sources of emf by replacing their internal resistances and calculate equivqalent resistance of the circuit.Lastly, join short circuit current source in parallel with equivalent resistance of the circuit. Now, we can calculate votage across the resistance which was connected in parallel with Isc.So, by knowing the open circuit voltage, we can calculate current flowing the resistance and on the other hand , by knowing the short curcuit current , we can calculate voltage across the resistance.
What is difference between VCB and ACB?
VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
What is rectifier and what is its use?
rectifier, it is a n electrical device that converts ths high votage carrying AC to low voltage carrying DC
Why voltage drop is negligible in ht side?
Because the current is smal , the votage > current x ressistance willbe small and therefore will be only a smal percentage of the ht.

How is DC votage represented on multimemters?
it is represented as DC-1000.
Is 380 votage considered 50hz or 60hz?
Voltage has nothing to with frequency
What is impulse votage?
Sudden rise in Voltage is called Impulse voltage.
Name a processor that requires dual voltage?
The Pentium MMX uses a core voltage of 2.8 volts and I/0 votage of 3.3 volts. For this proccesor one votage is used for external operations and another for internal operations.
