Hey, I need the answers to these questions. It's urgent. Don't critically evaluate. but don't forget to suggest applications

LED flashlights use "white" LEDs which have a diode voltage drop of 4.0V. A LED flashlight has the circuit illustrated and will run off several AAA batteries that have a 1.5 VDC rating. a. What is the minimum number of AAA cells needed to turn on the flashlight. b. Would you arrange the batteries in parallel or in series? Vdd R + LED V fritzing

Two storage batteries A and B are connected in parallel for charging from a DC source having anopen circuit voltage of 14V and an internal resistance of 0.15 ohm. The open circuit voltage of A is11V and that of B is 11.5V. The internal resistances of A and B are 0.06 ohm and 0.05 ohmrespectively. Calculate the initial charging currents.

3. Based on an old quiz problem related to half-wave rectifièr design. You may need your design if we have cold weather this winter. for charging your 12 VDC car battery. You are to design a battery eharger for safe operation in a damp garage environment to use RI Current Ling Resor R1 TXI Fuse 12 Vot Car Bater Metal Case Design specifications include: (a) Input is a 110rms VAC. (Vp=110x v2) at 60 Hz from a three wire service that meets the National Electrical Code. (b) Output is a nominal 12 volts VDC at the cathode of the diode. (c) Specify a resistor, R, to limit the maximum battery charging current to 10 amperes into the 12 volt car battery assuming the battery is completely dead (0 volts) when you first connect the charger. A not uncommon occurrence over the last two weeks of sub-zero temperatures. (d) There is no ripple voltage design specification. Explain why this is unnecessary in this application. (e) The battery charger case is metal. (f) Assume a diode with VF= 0.7 V (g)…

The counter in the given figure is ………….

Your team is building a robot that is powered with a 35Ah battery. During testing, the robot will run for a maximum of 5 hours before running out of battery, interrupting testing. The team would like to have a better idea of when the robot is going to run out of battery and needs to be recharged. An electrical engineer on your team designs a board to help solve this, with an LTC2944 and a 0.3mohm sense resistor. You are tasked with writing the software to read the accumulated battery discharge, in mAh, at the highest resolution possible. What should register bits B[5:3] be set to, in hexadecimal (please omit ‘0x’ from your answer)? Look up the datasheet to answer this question.

Find voltage regulation in typing format please ASAP for the like

i) Create the simplified circuit for the ‘A’ segment. ii) In the same work space, create the simplified circuits for the ‘B’ and ‘C’ segments . Note: You are putting all circuit in the same work space because you will need to join all the different parts together at the end. Take a picture or screenshot and include here. iii) Connect the 3 circuits in i) and ii) simultaneously to produce the number 7. You will need to set the inputs W,X,Y,Z to 0, 1, 1, 1 respectively. Take a picture or screenshot of the circuit (with the LED display) and include it here.

Help pls. I will upvote, Thankyou :)

Help me answer, I want to check my solution To get the contribution of the 75V source to iR, we first kill the 50mA source. What is the resulting equivalent resistance in series with the 75K resistor (in Kohms)  To get the contribution of the 75V source to iR, we first kill the 50mA source. What is the resulting value of iR (in mA)? What is the nodal equation for Vx? What is the Thevanin voltage in (Volts) and Thevanin resistance in (Kohms)?
