  b. The current of the group of batteries increases.
  c. Both the voltage and current of the group of batteries increases.

 Q. 2

When batteries are connected in series ___________
 
  a. The voltage of the group of batteries increases.
  b. The current of the group of batteries increases.
  c. Both the voltage and current of the group of batteries increases.

 Q. 3

Explain the function of the capacitor and inductor in solar energy controller.
 
  What will be an ideal response?

 Q. 4

Voltage in a parallel circuit ___________
 
  a. increases as additional resistors are added in parallel.
  b. decreases as additional resistors are added in parallel.
  c. stays the same across parallel branches as additional resistors are added in parallel.

 Q. 5

If a temperature control switch, high-pressure switch, and oil level switch are connected in series with a hydraulic motor and the oil level switch is opened because of low oil level, the motor will ___________
 
  a. still run because two of the other switches are still closed.
  b. not be affected because no other loads are connected to it in series.
  c. stop running because current flow will be zero.

 Q. 6

The capacitors and inductors filter the AC power. The capacitors filter the AC voltage, and the inductors filter the AC current. The capacitors can also be used to help correct the power factor for the system

Variable voltage inverter (VVI) A variable-voltage inverter (VVI) is basically a six-step,
single-phase or three-phase inverter. The need to vary the amount of voltage to the load became necessary when
these inverter circuits were used in AC variable-frequency motor drives and welding circuits.

Pulse-Width Modulation Inverters. Another method of providing variable-voltage and variable-frequency control for inverters is to use pulse-width modulation (PWM) control. This type of control uses transistors that are turned on and off at a variety of frequencies. This provides a unique waveform that makes multiple square-wave cycles that are turned on and off at specific times to give the overall appearance of a sine wave. The outline of the waveform actually looks very similar to the six-step inverter signal.
