Question

The charger for your electronic devices is a transformer. Suppose a 60 Hz outlet voltage of 120 V needs to be reduced to a device voltage of 3.0 V. The side of the transformer attached to the electronic device has 45 turns of wire.

Part A

How many turns are on the side that plugs into the outlet?

N = turns

    Answer:

    180 turns

    Explanation:

    Transformer: A transformer is an electrical device that operates based on the principle of electromagnetic induction.

    Using

    Ns/Np = Vs/Vp………………………… Equation 1

    Where Ns = Number of turns in the secondary coil, Np = Number of turns in the primary coil, Vs = Voltage in the secondary coil, Vp = Voltage in the primary coil

    Make Np the subject of the equation

    Np = Ns(Vp/Vs)………………. Equation 2

    Given: Ns = 45 turns, Vp = 120 V, Vs = 30 V

    Substitute into equation 2

    Np = 45(120/30)

    Np = 180 turns.

    Answer:

    NP=180Turns

    Explanation:

    Step one :

    Given data

    VP = the primary voltage. 120volts

    VS = the secondary voltage. 30volts

    NP = the number of turns in the primary winding.???

    NS = the number of turns in the secondary winding. 45 turns

    Step two :

    Using the formula

    NP/NS = VP/VS

    NP/45 = 120/30

    multiplying both sides by 45 to make NP subject of formula we have

    NP=(120/30)*45

    NP=(4)*45

    NP=180Turns

    A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle.

    There are two types of transformers

    Step up transformer

    Step down transformer
