Flashcards do conjunto (8)
- 1What is the equation for charge flow?Charge flow = current x time Q = It
- 2What is Ohm's law? (Equation for potential difference)Potential difference = Current x resistance
V=IR - 3What is the total resistance of two resistors R1 and R2 in series?total resistance (series) = R1 + R2
- 4What is the total resistors of two resistors R1 and R2 in parallel?1/R(parallel) = 1/R1 + 1/R2
- 5What is electrical power in terms of potential difference?Power = potential difference x current
P=IV - 6What is electrical power in terms of resistance and current?Power = current^2 x resistance
P=I^2 R - 7What is energy transferred in terms of power?Energy transferred = power x time E=Pt
- 8What is energy transferred in terms of charge flow?charge flow x potential difference
E=QV
