1.5 V battery. Determine experimentally the value of a resistor that when placed across the battery will make a measurable change in measured battery voltage. Keep the voltage decrease from open circuit value to 10% or less. example: the loaded (external resistor across the battery) battery voltage should be >= 90% of the open circuit value. Calculate the internal resistance of the battery.
(a) What is the tension in the coupling between the first car and the locomotive? (b) If this tension is equal to the maximum force the locomotive can exert on the train, what is the steepest grade up which the locomotive can pull the train at 25 ..
A micrometer caliper is used to measure the diameter of a bolt and a reading of 0.768 inches is obtained. Based on this measurement, find the smallest possible diameter and the largest possible diameter.
A.) We would like to use a series lumped element b to match this load. What is the length of the line where the normalized input impedance is z= 1-jb(d/\lambda). If the rfequency is 1GHz , find the value of the lumped element(C or L).
How do you write Kirchhoff's voltage law equation for a circuit.
What will be the output voltage from the bridge for a change in temperature of 20o C The supply voltage to the bridge is 6.0 V and the temperature coefficient of resistance of the platinum is 0.0039 K-1.
You are working with a design team on a new product and are assigned to design the power supply. The requirements for the power supply are as follows: Input AC: 115 V AC +- 10%, 50-60 Hz Outputs: +5 V DC at 100 ma, +-12 V DC at 50 ma
1.5V battery. Design a voltage divider to provide a voltage that is approximately 1/3 of the battery voltage. Use resistances in the kilo ohms range. Redesign your divider so that the resistors are in Mega ohms range.
A 150 MVA, 24 kV, 123% three-phase synchronous generator carries the rated load at a power factor 0.83 (lagging). Calculate the necessary excitation voltage and input complex power.
Explain why it is unlikely one would encounter a circuit exhibiting a critically damped response in practice. What impact would time and temperature have on a supposedly "critically damped" circuit
Design a logic circuit to produce a high output only if the input, represented by a 4-bit binary number, is greater than twelve or less than three. Implement a minimized circuit using only NAND gates.
General questions for network communications, A user message is split into 15 frames, each of which has an 80% chance of arriving error-free. If no error control is used by the data link layer, how many times must the message be sent on the averag..
