QI) For the circuits shown in figure below, obtain the equivalent resistance at terminals a-b. 200

(a) defibrillator sends a 6 A current through the chest of a patient by applying a 11000 V potential as in the figure. What is the resistance of the path (through the wire and the body)? -aira R= (b) The defibrillator paddles make contact with the patient through a conducting gel that greatly reduces the path resistance. To understand the importance of using the gel, discuss the difficulties that would ensue if a larger voltage were used to produce the same current through the patient, but with the path having perhaps 50 times the resistance by finding the ratio, P no-gel P gel e- ΚΩ (Hint: The current must be about the same, so a higher voltage would imply greater power. Use this equation for power: P = PR.) What difficulties arise when no gel is used? a. The voltage is too high for the human body even when the current is the same. b. There is a risk of skin burns because of the high power deposited.

What is the value of Vgs, when Id is.10 ?constant reference voltage Vdd =12V @

A potentiometer consisting of a wire of length L0 has a source of emf, ɛ connected across it. When a standard cell with emf V = 6V, in series with a voltmeter, is connected at one end of the wire and at a distance L = 4 cm along the wire the voltmeter circuit is in balance and the voltmeter reads zero. When the standard cell is replaced by a source of unknown emf the new balance length is found to be 6 cm. What is the unknown emf?       Select one: a. 9 V b. 8 V c. 4 V d. 3 V

Find the equivalent resistsmce qnd the power dissipated in the 1 ogm resistor using current division and voltage division ONLY

Explore the concept of duality in electrical circuits, where voltage and current are dual variables. How does this concept apply to circuit analysis?

Consider the series-parallel circuit shown in the figure below with various multimeters connected in the circuit. Assum that XMM1 has been configured in ammeter mode, and XMM2 has been configured in voltmeter mode. XMM1 R1 1kQ XMM2 R2 R3 V1 1kQ 1kQ 12V 3.1: Redraw the circuit replacing XMM1 and XMM2 by their equivalent circuit models 3.2: Assume that XMM2 was incorrectly configured in ammeter mode. Redraw the equivalent circuit from 3.1 and compute the current that would be measured by the ammeter in this scenario. Hil-
