Students have asked these similar questions
When the electromotive force is removed from a circuit Containing
inductance and resistance but no capacitors, the rate of decrease of the
current is proportional to the current. If the initial current is 30 amp and
it's down to 1 amp after 0.01 sec, what is the current after 0.03 sec?
Example 2: calculate the RMS noise voltage arising from thermal noise in two resistors
100 & 150 resp. at T= 300°K within a bandwidth of IMHZ if:
a- The resistors are connected in series.
b- The resistors are connected in parallel.
Example Question 1
A dynamometer-type AC ammeter made of moving coils and fixed coils with a shunt is used
to measure current. The ammeter is designed to let 95% of the input curent flow through the
shunt resistor. The moving coil's resistance is 10 2, and the shunt resistance is 0.004 2.
The Table Q1 below gives the relation between the deflection and the mutual inductance of
the ammeter.

(ii)
(iii)
the current passing through the moving coil at full-scale deflection,
the deflecting torque that gives full-scale deflection,
the current passing through the fixed coil at half-scale deflection.
(Hint: Plot the Mutual Inductance vs. Deflection graph based on the table above. Then, use the
graph to solve parts (ii) and (iii))

Condensate exiting the closed feedwater heater as saturated liquid at 500 lbf/in.² undergoes a throttling process to 120 lbf/in.² as it passes through a trap into the open feedwater heater. The feedwater leaves the closed feedwater heater at 1400 lbf/in.2 and a temperature equal to the saturation temperature at 500 lbf/in.2 The remaining steam is reheated to 800°F before entering the second-stage turbine, where it expands to 120 lbf/in.2 Some of the steam is extracted and diverted to the open feedwater heater operating at 120 lbf/in.2 Saturated liquid exits the open feedwater heater at 120 lbf/in.² The remaining steam expands through the third-stage turbine to the condenser pressure of 2 lbf/in.2…arrow_forward
