4. Consider a stepper motor with two phases. Phase 1 is wound with two identical coils. Phase 2 is also wound with two identical coils. Therefore, there are eight wires that come out from the stator winding, four for each phase (a) Connect the phase terminal wires in such a way that the motor can be used as a unipolar wound motor and draw:a schematics for the amplifier circuit of the motor windings (b) Connect the phase terminal wires in...

a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...

All elect lie healer has the resistance R = 10ohm. Two identical electric heaters are connected in series, and then connected to the electrical source with potential difference AV = 115 1V. Calculate the total electric power consumed by the two heaters "in-series". Two identical electric heaters are connected in parallel, and then connected to the electrical source with potential difference delta V = 115 Calculate the total electric power consumed by the two heaters "in-parallel". Answer, how the two...

Two identical resistors, R1 and R2, are
connected in parallel, and this parallel combination is then
connected in series with a 100 Ω resistor, R3 as shown
below
If the total resistance of the circuit is 300 Ω what must be the
resistance of R1 and R2? If the circuit is
connected to a 30V battery, what would the current through
R1? What voltage is a dropped across R3?

Question 5 1 pts Two identical capacitors (each of capacitance C) in series are connected to the battery. The third capacitor of capacitance 2C at some moment is connected in parallel to the first two. Adding this third capacitor will keep the charge on first two the same will increase charge on first two capacitors somehow change the charge on the first two capacitors, but impossible to predict how. will decrase charge on first two capacitors
