Question | Answer |
---|---|
DEFINE VOLTS | Voltage is the amount of electrical potential difference. Volts is V. Voltage is the amount of EPE per unit of charge at a point in a circuit compared to the PE per unit of charge at another point. Check volts before an after one point in the circuit |
DEFINE AMPS | Amps are amperes (A). They measure electric current passing a specific point in an electric circuit per second. Measured using an ammeter. The sign for current is I |
DEFINE OHMS | Ohms measure electrical resistance. The sign for resistance is R |
DEFINE WATTS | Watts measure power (W). The sign for power is P. |
DEFINE JOULE | Joule are units of energy (J). The sign for energy is E. |
OHM'S LAW | Measures the mathematical relationship between voltage current and resistance. |
DEFINE COLOUMB |
