For the given circuit, find the currents and (a) right after switch S is closed and (b) a long time after switch S has been closed. Let's now assume that the switch has been closed for a long time, and we agair open the switch. (c) find the three currents right after the switch is open, and (d) find the potential drop across the resistor R2. (e) What would be values of all three currents a long time after switch S was opened second time? R=1202 L=3M

(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.

Suppose the three branch currents in this circuit are I1 = -3 A, I2 = -18 A, and I3 = -15 A. The voltage drop across each circuit element is as given in the table below. From this information, determine, for each of these circuit elements, (i) whether an active or passive sign convention is being used for that element, (ii) whether that element is absorbing or producing a net (positive) amount of electrical power. In each answer box within the table below, type the correct choice from among the bold-faced words above. V2 B A B A C D 11 A B 12 12 + Circuit element Voltage drop Sign convention? Absorbing or producing net electrical power? -9 V -2 V C 9 V -11 V D

1.4 The charge cycle shown in Figure PL4 is an example of a three-rate charge. The current is held constant at 30 mA for 6 h. Then it is switched to 20 mA for the next 3 h. Find: a.

The energy transferred to the battery.Page 58 Hint: Recall that energy w is the integral of power, or P = dw/dr. 1.7 V 1.2 V 9.6V 05 V 30 mA 20 mA Figure P14 3h 3h 6h 6h 9h 7

can someone help me with parts A-C and explain the concepts for the slope parts explain how exactly you are getting those numbers

You are an electrician working on an overhead crane. The crane uses a large electromagnet to pick up large metal pipes. The magnet must have a minimum of 200 VDC to operate properly. The crane has an AC source of 240 V. You are given four diodes that have a peak voltage rating of 400 V each. These diodes are to be used to form a bridge rectifier to convert the AC voltage into DC voltage. Is the voltage rating of the diodes sufficient? To the nearest volt, what will be the DC output voltage of the bridge rectifier?

Find the potential difference between point a and point b for the situation shown below. Here 1 = 12.0 V, E2 = 8.77 V and R1 = 4.13, R2 = 5.44 , and R3 = 2.28 0. Va - Vb = R2 V R3 R1 W
