MPPGCL JE Electrical Mock Test - 2 - Electrical Engineering (EE) MCQ

Gauss is the great mathematician who is credited with discovering the total value of the first 100 natural numbers.

As 'Ophthalmia' is a disease of 'Eye' in the same way 'Rickets' is the disease of 'Bone'.

P is male member and married to Q.
P is husband and Q is wife.
R is brother of P.
S is the son of R.
T, who is the sister of S will be daughter of R.
Q is the daughter-in-law of U, whose husband has died means U is the mother of P.

Given:

Speed of train₁ = 32 km/h

Speed of train₂ = 40 km/h

Length of train₁ = 132 m

Length of train₂ = 108 m

Formula used:

If bodies moving in opposite direction = (x + y) km/h

If bodies moving in same direction = (x – y) km/h

Speed = Distance/Time

1 km/h = (5/18) m/sec

Calculation:

The sum of the length of the train = (132 + 108) m

⇒ 240m

According to the question

Relative speed = (32 + 40) km/h

⇒ 72 km/h

⇒ (72 × 5/18) m/sec = 20 m/sec

Now,

Time taken = Total distance/Speed

⇒ (240/20) sec

⇒ 12 sec

∴ Required time is 12 sec

As 'Forest' and 'Vivarium' have the same meaning in the same 'Sea' and 'Aquarium' have the same meaning.

From the common explanation, we get O sits exactly opposite to Q.

Hence, Option B is correct.

Final Arrangement:

Common Explanation:

References:

M is sitting fourth to the right of N.

P is sitting second to the left of N.

Inferences:

From the above reference, we get the following arrangements:

References:

Q is sitting third to the right of S.

Inferences:

From the above reference, we get two different cases:

Case 1:

Case 2:

References:

S is not sitting beside P.

T is sitting second to the left of O.

O is not sitting beside M.

Inferences:

So, from this case 1 will be eliminated as S is not sitting beside P.

Thus, the final arrangement,

The Schottky also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. A silicon diode has a typical forward voltage of 600–700 mV, while the Schottky's forward voltage is 150–450 mV. This lower forward voltage requirement allows higher switching speeds and better system efficiency.

Most of the 3-phase loads (e.g. 3-phase induction motors) are balanced and, therefore, we use 3-phase, 3-wire system for balanced loads.

All the given vary with change in temperature. Their mathematical relation with temperature is given as:
→ ηi² = A₀T³.e(^-EGO/kT)
→ μ= T^-m ; m=2.5 for electrons and 2.7 for holes
→ σ = σ₀ [1+α(T-T_o)]
→ E_G(T) = E_G0 - βT

The instantaneous power can be obtained by multiplying the two. P =vi.

It can be seen from the diagram that in the angle interval 0 to ϕ, the voltage is positive but the current is negative and hence the power is negative. Similarly, in the angle interval π to π+ϕ the voltage is negative but the current is positive and hence the power is again negative.

In other regions the power is positive. Now we just have to find what time interval corresponds to phase difference ϕ. For this we use the formula,

Hence, the correct option is (A)

Hence, the correct option is (A)

Given-

Since 6 Ω and 8 Ω resistors are connected in parallel, therefore the voltage across them is the same i.e. 48 V.

Current through 6 Ω resistor = 48/6 A

= 8 A

Current through 8 Ω resistor = 48/8 A

= 6 A

Total current entering the circuit i = (8+6) A

i = 14 A

Hence, the correct option is (C).

Current flowing through resistor is zero because the bridge is in balanced condition.

then,

One type of control system in which the output has no influence or effect on the control action of the input signal is called an Open-loop system.

The voltage across all branches in a parallel circuit is the same as that of the source voltage. 
So, the voltage across the 10-ohm resistor and the open circuit is the same=100V.
Hence, the correct option is (A).

or when or when

Hence, the correct option is (C)

Hence, the correct option is (A)

Hence, the correct option is (C)

We know that,
