b.)Its quiescent current is low
The Class B amplifier is a push pull amplifier with 78.5% efficiency. The high efficiency is due to the absence of power consumption during idle time which simultaneously increases the efficiency.
percent yield
Percent efficiency is a measure of how well a system or process converts input resources into output results. It is calculated by dividing the actual output by the theoretical maximum output, then multiplying by 100 to express it as a percentage. A higher percent efficiency indicates a more effective use of resources in achieving desired outcomes.
Percent error = (actual value - theoretical value) / theoretical value * 100%
The relationship used to determine the percent yield of a chemical reaction is calculated by dividing the actual yield of a product by the theoretical yield, then multiplying by 100. This formula helps to determine the efficiency of a reaction by comparing the amount of product obtained to the amount that could be obtained under ideal conditions.
Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100
Experimental yield and actual yield refer to the same thing, which is the amount of product obtained from a chemical reaction in a laboratory setting. Percent yield, on the other hand, is a measure of the efficiency of a reaction and is calculated by comparing the actual yield to the theoretical yield.
No. No engine can be 100% efficient. The Carnot cycle is mathematically proven to provide an upper bound for efficiency. The efficiency of the Carnot cycle can be calculated from the formula:eta = 1 - Tc/THwhereis eta is efficiencyTc is the temperature of the heat sinkTH is the temperature of the heat source.The only way to make the (theoretical) efficiency 100% would be to have a heat sink at absolute zero (which is impossible due to the 2nd law of thermodynamics) or to have the heat source at a temperature of infinity (which is impossible due to the 1st law). Real engines always operate at an efficiency less than the theoretical because they operate on a less efficient cycle and/or posses real irreversibility in their operation. Consequently no engine - real or theoretical - can operate at 100% efficiency.
Percent yield is a term that compares the amount actually produced in a chemical reaction versus how much could have been produced had all the reactants reacted fully. Theoretical percent yield is always 100%, because theoretically, all of the reactants reacted.
The experimental percent oxygen may be lower than the theoretical percent oxygen due to factors such as experimental error, incomplete reactions, or impurities in the sample. Variability in experimental conditions can influence the accuracy of the results obtained.
The process you are describing is known as calculating the percent yield. It is a measure of how efficient a chemical reaction is by comparing the actual amount of product obtained (actual yield) with the maximum possible amount that could be obtained (theoretical yield) under ideal conditions.
The percent recovery test is related to the law of conservation of mass. It helps determine the efficiency of a chemical reaction or separation process by comparing the actual yield to the theoretical yield, which is based on stoichiometry.
