The primary coil of a transformer has N1 = 275 turns, and its secondary coil has N2 = 2,200 turns. If the input voltage across the primary coil is Δv = (160 V)sin ωt, what rms voltage is developed across the secondary coil?

Secondary voltage of transformer is 905.23 volt  

Explanation:

It is given number of turns in primary of transformer

Number of turns in secondary

Input voltage equation of the transformer

Here

For transformer we know that

Therefore secondary voltage of transformer is 905.23 volt

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

it has to be b, about 97 percent.
