can someone please check my sig figs and answers? i have two different answers for the last question but they are off by .40. thank you! A student set up the circuit shown to the right. Please use R1-2.00 ohms, R2-4.00 ohms, R3 -3.00 ohms, R 1.00 ohms, Rs 5.00 ohms, and a power supply setting of 6.00 volts. (a) Write the symbolic expressionoW Power Supply calculating the effective resistance of two resistors, R4 and Rs, in parallel. (b) Write...
Can someone help me with these? Thank you in advance! 1. The circuit shown here can't be reduced, since none of the resistors are connected in series or in parallel with each other. The unlabeled arrows show the direction of current in resistors 2, 4, and 5. Use Kirchhoff's junction or loop rules to answer questions (a)-(c) below. Show work for all calculations, and briefly explain your reasoning on current direction in (a) and (b). The symbols Ii, h, etc....
can someone show me how to do this please i think i was taught that when i want to find the output resistance then all i need to do is short circuit the input voltage and add a nominal voltage attached to Vout inorder relate with ohms law to find output resistance thank you (c) The small-signal equivalent circuit of a voltage follower is shown below in Fig. 2.3. (3 marks) Determine an expression for the small-signal output resistance of...

AL AK AZ AR CA TX MA Once the ArrayList is created do below operations 1. Add the state PA in the ArrayList at the end 2. Search through the ArrayList and replace the state CA with FL 3....
can you help me answer question #6 please the first circuit was series the second circuit was parallel and the third circuit was both thank you 4) Calculate the EXPECTED voltage through each resistor for each of the circuits (#1, 2) in PART II from the total current and the equivalent resistance. Calculate %error for one your measurements based on the calculated value from this question. 5) Calculate the EXPECTED current THROUGH EACH RESISITOR for each of the circuits (#1,...
Can someone help me with number 3 of my pchem homework? Uranium-lead dating is an important technique for determining the age of rocks that formed from about million years to over 4.5 billion years ago with routine precisions in the 0.1-1 percent range (according to Wikipedia). Uranium-235 decays according to actinium series: 235U207 Pb+7a +4B with a rate constant of 0.00097626 mition years I.) Determine the order, rate law, and integrated rate law for this decay process. 2. Determine the...
i)draw the transafer charcheristics for this circuit? ii)Derive expressions for VTH and VTL? iii)Let L+ = - L- = 10 V, and R1=1 k Ω , choose R2 in order to get a hysteresis of 100mV width? iv).An engineer decided to modify the given circuit by disconnecting the inverting input of the op-amp from the ground and connecting it to a constant voltage source Vx. Derive expressions for VTH and VTL and Draw the transfer characteristics in this case.? Question...
can someone please help me with this question. I've tried to solve it but I seem to get nowhere. A chopper is used in the regenerative braking of a dc series motor similar to the arrangement shown in Figure Q2. The armature resistance R = 0.02 and the field resistance Rp=0.032. The armature current is maintained at a constant value of la = 200 A The back emf constant Ko = 15.25 mV/A rad s. The dc supply voltage Vs...
