A given solar cell has the following specifications:
Open-circuit voltage, Voc: 0.7 V
Short-circuit current, Isc: 3.5 A
Short-circuit current, Isc: 3.5 A
Short-circuit current, Isc: 3.5 A
If the solar cell operates at maximum power point, calculate the efficiency.

Equation is given by:
Efficiency = (F.F*Voc*Isc)/Pin
= (0.6*3.5*0.7)/10
= 0.14702
% efficiency = 14.7 %

Recently, India signed first ever term contract to import crude oil with which country?

___ is the rms value of the total current comprising the AC and DC components of the current in the circuit breaker pole at the instant of contact separation.

Symmetrical breaking current:
It is the rms value of a a.c component of the current in the pole at the instant of contact separation.

Asymmetrical breaking current:
It is the rms value of the total current comprising the a.c and d.c components of the current in the pole at the instant of contact separation.

Murray loop test is performed on a faulty cable 300 m long. At balance, the resistance connected to the faulty core was set at 15 Ω and the resistance of the resistor connected to the sound core was 45 Ω. Calculate the distance of the fault point from the test end.

Where,
R2 is the resistance connected to the faulty core in ohm
R2 is the resistance of the resistor connected to the sound core in ohm

R1 Distance of fault location (Lx) = R2/(R1 + R2)*(2*L)
= (15/60)*600
= 150 m
