Answer: Ohm Ω
Explanation:
The resistance can be defined as the hindrance offered to the flow of current. Lower the current the higher is the resistance. The SI unit of resistance is ohm Ω. When one ampere current flows from an object or wire the application of one volt of potential difference on it the resistance so produce is one ohm. Resistance can be achieved by the application of the certain gadgets in the circuit which can prevent the flow of excess current from devices and can prevent shock circuit.

How do we define energy efficiency?
А.) the ratio of the actual output energy to the input energy
B.) the ratio of power gain to power loss
C.) the product of input power and output power
D.) the sum of potential and kinetic energy
Answer:
a
Explanation:
that is what energy efficiency is
Consider one-dimensional heat conduction through a large plane wall with no heat generation that is perfectly insulated on one side and is subjected to convection and radiation on the other side. It is claimed that under steady conditions, the temperature in a plane wall must be uniform (the same everywhere). Is this claim reasonable
Answer:
YES, this claim reasonable
Explanation:
the temperature in a plane wall is uniform since no heat is penetrating into the large plane wall and therefore, there is no heat transfer from the wall under steady conditions,
This condition will be met only when there are no temperature differences within the wall and the the outer surface temperature of the wall is equal to the temperature of its surrounding.
Therefore, Yes, this claim is reasonable
