Independent sources are represented by?
Explanation: Independent sources are represented by circle
Dependent sources are represented by?
Explanation: Dependent sources are represented by Diamond.
Independent sources are also known as?
A. Controlled sources
B. Voltage sources
C. Ideal sources
D. All of the above
Explanation: Voltage V = dw/dq and its SI unit is Volt.
Which element means it could not generate electricity?
Explanation: Passive element means it could not generate electricity
Inductor is _______________ element.
Explanation: Inductor is Passive element.
The below circuit is valid?
C. Can be true or false
D. Can not say
Explanation: Independent current source supplied current through terminals a and b. Dependent source supplies voltage across the same pair of terminals and an ideal current source supplies same current regardless of voltage, similarly an ideal voltage source supplies same voltage irrespective of current, so this is an allowable connection.
The opposing capacity of materials against the current flow is?
Explanation: The opposing capacity of materials against the current flow is resistance.
The conductance of a 923Ω resistance is
A. 1.08 * (10^-3) mho
B. 1.08 * (10^-4) mho
C. 1.08 * (10^-2) mho
D. 1.08 * (10^-1) mho
Explanation: c=1/R =1/923 = 1.08 * (10^-3) mho
Relation between power, voltage and conductance
A. V = (P^2).G
B. V = (P^2)/G
C. P = (V^2).G
D. P = (V^2)/G
Explanation: P = vi => v (v/R) => (v^2)/R => (v^2)G.
Which of the above is valid?
C. Both Valid
D. Neither 1 nor 2
Explanation: Same Voltage
