10.1 Define a transformer. A transformer is a device that is used to step up or step down the voltage. 10.2 Determine the value of the secondary voltage. To find the secondary voltage, we can use the transformer equation: $$V_s = V_p \cdot \frac{N_s}{N_p}$$ Given: - Primary voltage, $V_p = 120 V$ - Number of turns on the primary coil, $N_p = 80$ - Number of turns on the secondary coil, $N_s = 1500$ Thus, substituting the values: $$V_s = 120 \cdot \frac{1500}{80} = 2250 V$$ 10.3 Study the diagram below and answer the questions that follow. Identify the type of generator represented by: 10.3.1 FIGURE 1 10.3.2 FIGURE 2 Label component: 10.3.3 A 10.3.4 B State the function of component A.

Answer

To find the secondary voltage, we can use the transformer equation:

$V_s = V_p \cdot \frac{N_s}{N_p}$

Given:

Primary voltage, $V_p = 120 V$
Number of turns on the primary coil, $N_p = 80$
Number of turns on the secondary coil, $N_s = 1500$

Thus, substituting the values:

$V_s = 120 \cdot \frac{1500}{80} = 2250 V$
