L1-11A.15 – AC or DC Voltage can be direct or alternating. A direct voltage maintains the same polarity at all times. In an alternating voltage, the polarity reverses direction periodically. An example of direct voltage is the potential difference between the...
L1-11A.13 – Power = Watts = VA Is a value of the actual “work” being done by the electricity Is found by multiplying Volts times Amps (thus the VA) Is measured in Watts Symbol is “P”,“W” or...
L1-11A.12 – Measuring Electricity Voltage= Motivation –Force- Pressure Measured on Volts (V) Symbol in equation is “E” Current= How much Measured in Amps (A) Symbol in equation is “I” Resistance= Obstacles Measured in Ohms (Ω) Symbol in equations...
