The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.

Is unit step signal is bounded or unbounded?
bounded signal
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
What does a transformer do to a voltage in a power line?
A transformer is used to step up (increase) or step down (decrease) an alternating voltage with very little loss of energy.
What is unit transformer?
UniT transformer are step up transformer which is connected to generating house & step up voltage from 11/15kV votlage to 220/400kV voltage level as requirement or line design parameter. It is just like transformer but connected to unit of the generating house that's why we called it unit transformers.
What is an example of a step-up transformer?
Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
What is periodicity of unit step signal?
YES, unit step function is periodic because its power is finite that is 1/2.. and having infinite energy.
Is exponential signal an energy signal or power signal?
If the signal is not bounded by a step function, then an exponential signal is neither a power nor an energy signal. So the answer is neither.
How you can determine whether signal is power signal or energy signal?
A signal x(t) is called an energy signal , if the energy is finite and the power is zero.A signal x(t) is called an power signal , if the power is finite and the energy is infinite.
What is the unit step signal?

Is unit step signal is bounded or unbounded?
bounded signal
How transformer converts mva to kv?
Transformer does not convert MVA to KV. MVA is unit of power, where as KV is unit of Voltage. Transformer converts voltgae. Step up or Step down.
Why do soldiers route step?
route step is a longer stride of a step at a faster pase,that allows a unit of men to move from one place to another, while conserving energy by not running.
Is step signal is a DC signal?
A: while a step can be of both polarity but it is a level change and it is DC LEVELS
What is the name of a step-up which increases the voltage of electric energy that is generated at a power?
An electrical transformer can step up (or step down) the voltage.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Why transformer is not called an amplifier?
In an ideal transformer the power in equals the power out there is no gain. In an ideal amplifier the power out equals the Gain *Power In. An ideal transformer transforms energy at a ratio of its windings. For example an ideal 1:10 ratio transformer (step up) would convert a 10Volt input at 10amps to a 100Volt output at 1Amp. Or conversely an ideal 10:1 ratio transformer (step down) would convert a 10Volt 10Amp input into a 1Volt 100Amp output. Since Power = Voltage * Current we can see the power in equals the power out in an ideal transformer. In an ideal amplifier the power out is greater than the power in. This is defined as the gain of the amplifier. An ideal amplifier with a Voltage gain of 10 would take a 1Volt 1amp signal and amplify it into a 10Volt 1 amp signal. An ideal amplifier with a Current gain of 10 would take a 1Volt 1Amp signal and amplify it into a 1Volt 10 amp signal. Since Power = Voltage * current we can see the power in is less than the power out showing a gain in power.
How is coil a transfer of energy?
Coil is a transfer of energy because it takes energy to make coil burn which is reduced as heat/ light energyMy VersionA electrical coil will step up (convert) voltage and electrical energy or step down depending on how it is designed. EG: A coil called a transformer will take the 600 volt power from the power grid and turn it into 120 volt power in your house.
