10 points that I learned

Interesting depiction of the alternating/direct current along with other types

-The equation I = Q/T where I is the current in amperes, Q is the charge in coulombs and t is the time in seconds.

-An anmeter is a current-measuring device that must be an excellent conductor so that its presence does not disrupt the flow of the current (i.e. loses energy)

-If you make a mistake in the wiring of an anmeter, you may cause burn outs or sparks depending on the different types of anmeters and the different mistakes you make.

-How to illustrate different parts of a circuit quickly with many circuit symbols, such as cells, DC and AC generators, cells in series, resistors, transformers and anmeters.

-The equation V = E/Q where E is the energy required to increase the electric potential of a change, Q being the charge, and V being the electric potential difference.

-Electric potential difference uses the unit, volt, which is named after Count Alessandro Volta.

-Potential difference can be measured using a voltmeter. The voltmeter must be connected in parallel with a load so that the potential before and after the load may be compared.

-Unlike the anmeter, which must be an excellent conductor, the voltmeter must be a poor conductor. The reasoning behind this is that the poorer conductor, the voltmeter, will divert a minimal current from the circuit when it is measuring the potential difference.

-There are 2 types of currents, DC and AC. DC or direct currents flow in one direction all the way from the power source (ex. Battery) to the load (ex. Light bulb). AC or alternating currents change the direction of its flow periodically.

-Direct currents do not last as long as alternating currents therefore alternating currents are better. However, some loads do not support going both ways and can only use direct currents.
