Introduction to Circuitry

Ohm's Law

German Scientist Georg Simon Ohm discovered that the ratio between the potential difference (voltage) to the current is is equal to the resistance, or when rearranged, V=IR. The electric current, I, is measured in Amperes, potiential difference, V, is measured in Volts, and resistance, R, is measured in ohms.

Circuits

Circuits comprise closed wiring through which electrical currents are capable of flowing. They tend to have switches that open and close the circuit in order to either stop the current or allow it to flow through the circuit. Circuits can be found in every day life and connect all household appliances. A switch that opens and closes a circuit could be something like a light switch that turns the light on and off.

There are two types of identifiable circuits that we have learned so far in Mr. GK’s wonderful world of Physics.  These two types are Series Circuits, the simpler of the two, and Parallel circuits, the ones most likely to be found in your home.
