Larry uses a transformer to step down an incoming voltage. The transformer has ten loops in the primary coil and six in the secondary. If the incoming voltage is 120 volts, what is the outgoing voltage?
A. 720
B. 72
C. 200
D. 20

Sagot :

ardni313

The outgoing voltage : 72 V

Further explanation

Given

Vp=primary=120 V

Np=10

Ns=6

Required

the secondary voltage

Solution

[tex]\tt \dfrac{V_p}{V_s}=\dfrac{N_p}{N_s}[/tex]

Input the value :

[tex]\tt \dfrac{120}{V_s}=\dfrac{10}{6}\\\\V_s=\dfrac{120\times 6}{10}=72~V[/tex]
