Compare and contrast series and parallel circuits?
Cost = 0.825 x .08 = $0.066
Term = Voltage, Unit Name = Volts, Unit symbol = V
series circuit is open the entire circuit goes out. If a branch of a parallel circuit is open, only that branch goes out
brightness of all bulbs will dim bc adding another bulb increases the overall resistance/reduces current I=V/R
E = Pt
Term = Power, Unit Name = Watts, Unit symbol = W
Resistance is equal to the voltage divided by the current. (R= V/I)
P = IV = 8.5x240 = 2040 W
The variable P in a formula is what?
