Quiz 3 Flashcards
Ohm’s law V-, V=
- power source/volts
* V= I x R
OHM’s law I-, I=
- I-current (in amps)
* I=V/R
OHM’S law R-, R=
- R- Resistance in OHMS
* R=V/I
Circuit components -| I | I | -
•Battery
Circuit components — straight line
•conductor
Circuit components —VVVVVV—
•load resistance
Current in circuit series
•remains the same throughout circuit
Power source in a series circuit
• adding total voltage equals total power source
Total resistance for parallel circuit
- Reciprocal
- 1/R= 1/R1+1/R2+1/R3
- find the LCD of the denominator
- what ever u do to the bottom u do to the top
- add numerators. Over LCD
- flip so LCD is over numerators
- = resistance in OHMS
What stays constant/the same in a series circuit
•current (amperage)
If power source is an series how do u find total voltage
•u add the all voltages together
What is constant in a parallel circuit
- total voltage
* voltage drop
Power loss (formula)
- heat loss
- proportional to resistance
- P=i(square) x R
- power=Amp(square) x Resistance

2 things that make current flow?
- EMF
* Voltage
Fluctuation of current but same amount of voltage is?
•parallel circuit
EMF
- electric motor force
* what makes current move
How to find Total resistance on a series circuit
•add all the individual resistance = total resistance
Fluctuations of voltage but same amount of current is
•series circuit
Shell with lowest energy level
