Why is it important for Boolean expressions to be minimized in the design of digital circuits?

1.to make circuit to be smaller hence less number of logic gate. 2.reduces propagation. 3.reduces error. 4.implementing the expression in circuit form.


Why must resistance never be measured in an active circuit?

First of all, in an active circuit, there are voltages flowing through various nodes. If you try to measure the resistor, those voltages will cause error in your meter, or may damage your meter. Second of all, even if you cut the power, any loop in the circuit around the resistor will affect the measured impedance. Unless you are certain that only the resistor will see the current introduced by the meter, you must take the resistor out of circuit to measure it.


Experimental error caused by instrumental limitations?

Error caused by instrumental limitations is actually called systematic error, not experimental error.


Why voltmeter should have a very high resistance?

well a voltmeter measures AC and DC voltage. resistance is a term used only for DC voltage, A voltmeter uses a term called Impedance for AC, without it, when you measure across two terminals it would create a short circuit and would blow up the meter. it is basically a safety feature to prevent people from creating short circuits when measuring.


Why do you abbreviate circuit as ckt?

This abbreviation comes from the 1950s US Navy electrical shipyards assemblies. It was used to abbreviate what was then called "Circuit Breakers". This is how the "K" crawled in. Today these parts are simply called connectors or headers but the abbreviation stuck since. Many say that it is a mere spelling error, but the fact is that English abbreviations are often misspelled compared to their origin words, for example - OK abbreviates "All Correct".

What is voltage error circuit and current error circuit?

A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.

Why won't the switch on my breaker box stay on?

This is properly understood when Ohm's Law is applied: Voltage, Amperege and Resistance are correctly applied to a circuit for it's correct function. The circuit breaker acts as a protective device and trips when a correct electrical circuit does not exist. The wrong breaker may have been installed. the wrong gauge of wire may have been used, the pumps and heaters may be drawing more amps then planned for or a short circuit or loose connection are all possible faults. Contact the electrician that installed the system for resolution of the problem or an outside electrician if the problem isn't corrected. Caution: Water and Electricity should not be trusted when in close proximity.


The light on my gfi outlet is dim and sometimes out i am getting no power to it but the circuit breaker is not tripped i just replaced the gfi and it didn't help any ideas?

If the GFI outlet is tripped (the outlet, not the breaker) then it is telling you there is a ground fault which must be fixed. If the GFI outlet is not tripped, and the breaker is not tripped, but it is still not providing power, then you have a loose connection or a wiring error.
