How temperature effect conductivity? Explain with the help of following equation. m e'n7'

How about solving this using KCL equations? Thank you

b) Describe the traces you would see on an oscilloscope monitoring voltage changes across a resistance which has: - AC flowing through it - DC flowing through it You should include diagrams to support your descriptions for each trace.

Notes on the verification of ohm's law by voltage method?

Steady current circulation is desired for a lamp connected in a circuit to light. For this, explain how a stable current will occur from any part of the circuit with the conservation law of the charge. Give me detail pls.

What is GENERATION AND MEASUREMENT OF DC VOLTAGE? Give some introduction about it in 2 page if possible... High voltage engineering

Discuss the terms resistor, voltage, current and power withexamples.          plagarisim will be apply

The schematic is step 7

PLEASE ANSWER BOTH QUESTIONS FOR UPVOTES. NO UPVOTE IF ONLY ONE HAS AN ANSWER. PUT ONLY BRIEF EXPLANATIONS ON CHOOSING THE CORRECT ANSWERS. THANK YOU

Two electrical elements are connected in series. What can you say about the currents through the elements?

What is Resistance and inductance.

Electric Current and Resistance. What is an Electric Battery? Define electric current and state what is meant by the term conventional current. Describe Ohms's Law and draw an example using an I-V cuvre.

An example of Simple Resistive Circuits is ,

Electrical Engineering I'm reading about the electronics in touch screen. It says when i touch the panel it distorts the electrostatic field and thus will have a change in capacitance. This is how it detects My question is the electrostatic field same as electric field? Please explain in details How did the capacitance change when i just touch the panel

25/ Identify the statement from the following when the inductance can have low value. a. If the number of turns of the wire is less b. If the cross-sectional area is lesser c. If the length of the wire is longer d. All the given options

The semiconductors is a materials whose conductivity and resistivity is more than conductors and insulators true O False

The terminal potential difference will be greater than its emf when it is * In open circuit Being charged Being charged or discharged Being discharged

The work function for the anode is bigger than that of the cathode, resulting in a so-called "contact-potential difference" between the anode and cathode. Its effect is to shift the entire Current vs. Voltage curve (why?). Estimate the contact potential difference. 7

Ferrule has to be connected and ………….. in order to connect 2 underground cables

A device needs an output voltage of 28 volts full wave dc voltage. We have 4 diodes, one zener diode, one capacitor, one resistor and one 220v / 50v. There is a transformer. Load current 300 mA (maximum) How do you do this job with these materials? Write the appropriate values on them. Calculate with formulas. Draw the circuit.

An inductance of 2 henries and a resistancc of 20 ohms areconnected in series with an emfE volts. If the current is zerowhen t 0, find the current at the end of 0.01 sec if E = 100 volts.

(differential Equation Application) A resistance of 120 ohms and a capacitance of 0.01 Farad is connected in series with a 200 Volts battery. Find the current after 0.4 second.  BOX FINAL ANSWER

Okay for   Determine the mathematical expression for the voltage vC and the current iC for the discharge phase. I got Vc = 8e-t/0.2s V and iC = -4e-t/0.2mA But I need help with the last question Plot the waveforms of vC and iC for a period of time extending from 0to 2 s from when the switch was thrown into position 1.
