Electrical curcuits
Term | Definition |
---|---|
Ohm's Law | I=V/R I= Current (Amperes), V= Voltage (Volts), R= Resistance(Ohms) |
Voltage | A force that pushes the current through the circuit |
Resistance | Friction that impedes flow of current through the circuit |
Current | The actual "substance" that is flowing through the wires of the circuit |
Series Circuit | 1 path for electricity, if 1 light is out than the whole circuit is broken |
Parallel Circuit | Contains many paths and if 1 light is out the rest stay on |
Measuring currents | Electrical current is measured in amps (A) using an ammeter connected in series in the current |
Measuring voltage | Voltage is measured in volts (V) on a voltmeter |
