Quiz 3 Flashcards
1
Q
Ohm’s law V-, V=
A
- power source/volts
* V= I x R
2
Q
OHM’s law I-, I=
A
- I-current (in amps)
* I=V/R
3
Q
OHM’S law R-, R=
A
- R- Resistance in OHMS
* R=V/I
4
Q
Circuit components -| I | I | -
A
•Battery
5
Q
Circuit components — straight line
A
•conductor
6
Q
Circuit components —VVVVVV—
A
•load resistance
7
Q
Current in circuit series
A
•remains the same throughout circuit
8
Q
Power source in a series circuit
A
• adding total voltage equals total power source
9
Q
Total resistance for parallel circuit
A
- 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
10
Q
What stays constant/the same in a series circuit
A
•current (amperage)
11
Q
If power source is an series how do u find total voltage
A
•u add the all voltages together
12
Q
What is constant in a parallel circuit
A
- total voltage
* voltage drop
13
Q
Power loss (formula)
A
- heat loss
- proportional to resistance
- P=i(square) x R
- power=Amp(square) x Resistance
