21. According to Figure 2, the maximum positive value of Vs was approximately:
Answer and Explanation
Your Answer is
Correct Answer is C
Explanation
Look at figure 2, the maximum value of the vertical voltage on the right is about 250V
Passage IV
Figure 1 is a diagram of an RLC circuit. The circuit has a power supply and 3 components: a resistor (R), an inductor (L), and a capacitor (C).
Electric current can flow through the circuit either clockwise (positive current) or counterclockwise (negative current). Figure 2 shows how the electric current in the circuit, I (in amperes, A), and the power supply voltage, Vs (in volts, V), both changed during a 20-millisecond (msec) time interval.
Figure 3 shows how the voltages across the components—VR, VL, and VC, respectively—each changed during the same 20 msec time interval.
