alternating current (AC) module system; 2) interactive system; 3) hybrid system; and 4) stand-alone system. Although the diagrams help you identify the system components, circuits, and connections, ...

If the current flows in only one direction it is called direct current, or d.c. Batteries and solar cells supply d.c. electricity. A typical cell or battery may supply 1.5 V. The diagram shows an ...

Chapter 7: Alternating Current Question 1 ... Question 3: Draw the phasor diagram for an LCR circuit. Question 4: Explain the power factor and its significance in AC circuits.

Current transfers energy around circuits. Circuit components have various properties that can be measured and then used to make circuits for control and also circuits for testing other components.
