QUESTION 4

A transformer has 394 turns on the primary coil and 2,382 turns on the secondary coil. The RMS voltage on the primary is 120.0 volts, and the power delivered to the transformer is 33.0 watts. What is the RMS current (milliamps) output from the secondary coil? (State answer in milliamps with 1 digit right of decimal.)

QUESTION 5

Consider a series RLC circuit with a resistor R = 51.0 Ω, an inductor L = 2.28 mH, a capacitor C = 0.330 µF, and an AC source that provides 0.155 volts RMS at 17.1 kHz (kilohertz). What is the impedance (ohms) of the circuit? (State answer in ohms as a whole number with no decimal).

QUESTION 6

An object is placed 17.9 cm in front of a diverging lens of focal length -30.0 cm. A converging lens of focal length 16.0 cm is placed 12.9 cm after the first lens. Where is the location of the final image relative to the second lens? (State answer in centimeters with 1 digit right of decimal.)
