How would you show how to measure the percent efficiency of an amp?

The Percentage Efficency for an amp is calculated via the following formula,Percentage efficency = (0.5÷amperage)×100= (0.5÷1)×100= ± 10%


What is the formula for calculating the equivalent resistance of a series circuit?

Equivalent resistance of a series circuit is the sum of the resistance of all appliances. The formula is R=R1+R2+... where R is equivalent resistance, R1, R2 and so on is the resistance of the individual appliances.


What is the Q factor in RLC circuit?

It is related to damping in the circuit using a resistor. Q is inversely proportional to the resistor(R). So if the value of resistance is high, there is a greater damping and the value of Q will be low. if resistance is low, there is small damping and Q will be high. when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large. Go do some research on the graphs and the formula of Q factor to understand it better.


What is the value in ohms of a resistor colored red red yellow gold?

Using a resistor color code chart below, you will find that the resistance is calculated this way: Resistance = (1st Digit x 10 + 2nd Digit) x Multiplier Hold the resistor with the gold or silver band to the right and read the resistor from the left to the right. So, in this case, the resistor is: RED RED YELLOW GOLD Using the formula and resistor color chart found in the link below, the resistance would be: R = 1st Digit x 10 + 2nd Digit) x Multiplier R = (RED x 10 + RED) x YELLOW R = (2 x 10 + 2) x 10,000 R = 22 x 10,000 R = 220,000 ohm (220 K ohms) Since the final band is gold, the tolerance is 5%


A 5 ohm resistor a 20 ohm resistor and a 25 ohm resistor are all connected in series to a 100 volt power source What is the current running through the circuit?

To find the current running through the circuit, you need to use Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. You can use the following formula to calculate the current: I = V / R Where I is the current, V is the voltage, and R is the resistance. In this case, the total resistance of the circuit is the sum of the individual resistances, which is 5 ohms + 20 ohms + 25 ohms = 50 ohms. Therefore, the current flowing through the circuit is: I = 100 volts / 50 ohms = 2 amps.

How do you calculate percentage error for density of pennies?

Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.


What is the percentage error in p?

Percentage error in p is calculated by taking the absolute difference between the measured value and the true value, dividing by the true value, and then multiplying by 100 to get the percentage. The formula is |(measured value - true value) / true value| * 100.


Why elasticity of demand is measured in percentage?

Price elasticity can be precisely measured by dividing the percentage change on quantity demanded by the percentage change in price that caused it. Thus e can measure price elasticity by using the formula Price elasticity = Percentage change in quantity demanded ÷ percentage change in price


How do you calculate the percentage error in a measurement or calculation?

To calculate the percentage error in a measurement or calculation, you first find the difference between the measured or calculated value and the accepted or true value. Then, divide this difference by the accepted value and multiply by 100 to get the percentage error. The formula is: Percentage Error (Measured Value - Accepted Value / Accepted Value) x 100

What is the formula for percent error?

The formula of percent error ispercent error= Your value/accepted value x 100------------The definition of error is: difference between the accepted true value and the measured value of a quantity or parameter. But this is the absolute error.The relative (percent error) is:(measured value - accepted true value) . 100/accepted true valueThis value is exprssed as a percentage - %.


How can I find the energy dissipated in the resistor?

To find the energy dissipated in a resistor, you can use the formula: Energy (current)2 x resistance x time. This formula calculates the energy dissipated in the resistor based on the current flowing through it, the resistance of the resistor, and the time the current flows.


How do you calculate percentage error on weighing scales?

Percentage error on weighing scales is calculated by taking the absolute difference between the measured weight and the true weight, dividing it by the true weight, and then multiplying by 100 to get the percentage. The formula is: (|Measured weight - True weight| / True weight) * 100.


What is the expression of error as a percentage of the value?

The expression of error as a percentage of the value is calculated by taking the absolute value of the error (the difference between the measured value and the true value), dividing it by the true value, and then multiplying by 100. The formula is: [ \text{Percentage Error} = \left( \frac{|\text{Measured Value} - \text{True Value}|}{\text{True Value}} \right) \times 100 ] This provides a way to express how significant the error is relative to the true value.
