consider the following circuit composed of three resistors and two batteries. each resistor has a resistance of 2.00 ohms. assume that the branch currents flow in the directions indicated in the figure. note that: I = 0.600 A I = 0.800 A E1= 10.0V R1= 10 ohms R3= 5 ohms Solve: a.) Write out the equation relating the currents by using the junction rule at node a. Additionally, what is the magnitude of I3? b.) What is the resistance of R2? c.) what is E2?

Knowing the resistance of the resistors and the EMF of the sources, find the currents in the branches.Proceed comparative analysiswith calculation (equations) and mathematical analysis (Ansys). Create reports with calculations (current on each elements, voltage on each elements), screenshot from Ansys and conclusion. my c variant is 2

A Wheatstone bridge is used for measuriug the valuc of change of resistance of a strain gauge wnich forms one of the arms of the bridge. All tbe arms of the bridge including the strain gauge have a resistance of 100 N each. The maximum a!lowable power dissipation from the strain gauge is 250 mW. Determine the value of maximu:n permissible current through the strain gauge and maximum allowable value of bridge supply voltage. Suppose a source of 20 V is available, lind the value of series resistance to be connected between the source and the bridge to limit the input voltage of the bridge to permissible level.

Sample Problem continued with solution process Step 1: Drawing a circuit diagram and labeling the unknowns. All told there are 5 elements, 4 resistors and 1 voltage source. For resistors I intentionally label the currents going from + to -. That way, I can write V = I R. If I labeled the current through a resistor from – to + as I, then I have to write the equation by Ohm's law as V = -I R. For convenience I label the current i, through the voltage source from – to +. (There is no Ohm's law for a source to follow. Do not try to have a resistance in a source. What is a V, 3 + (1 |1A 10 Ω + V, iş V2 20 i2 V3 + 2 20Ω 4 İz I then examine the circuit. I see that this is a obvious consequence of the labeling: iz = i,= i, All are current going through one path with the same direction as I labeled. If I had labeled one in the opposite direction, I just had to put in a minus sign. source? A voltage source is to guarantee the voltage drop from its + to its – a fixed voltage V,. I denote four…

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. 8 V b. 9 V c. 4 V d. 3 V
