Conservation of energy requires that the sum of the power received by all of the elements in acircuit be zero. In the figure below, all of the elements voltages and currents are specified exceptone. Find the unknown voltage v1 in Volts of the element.5V-5 A9 V1 A8 VV1 V1 A4 A5 A+ 1 VHint: Calculate the power absorbed by each element. Add up all of these powers. If the sum is zero,conservation of energy is satisfied and the voltages and currents are probably correct. If the sum isnot zero, the element voltages and currents cannot be correct.

Compensation Techniques

The compensation techniques are the methods that are employed in the electrical control systems to enhance the performance of the system. The performance are generally affected by the factors like lag in the compensating devices, slow response of the system of the components like sensors used in the control system. The basic compensation technique involves lag compensation, lead compensation or the combination of the both.

Question

Conservation of energy requires that the sum of the power received by all of the elements in a
circuit be zero. In the figure below, all of the elements voltages and currents are specified except
one. Find the unknown voltage v1 in Volts of the element.
5V
-5 A
9 V
1 A
8 V

1 A
4 A
5 A
+ 1 V
Hint: Calculate the power absorbed by each element. Add up all of these powers. If the sum is zero,
conservation of energy is satisfied and the voltages and currents are probably correct. If the sum is
not zero, the element voltages and currents cannot be correct.
