New cards
Whats the difference between a series and parallel circuit?
2
New cards
Voltage in a series circuit is...
shared across all components, proportional to their resistance. DO THE RATIO. Total voltage / total resistance x resistance of component.
3
New cards
Current in a series circuit is...
the same everywhere.
4
New cards
I1 = I2 = I3
5
New cards
Resistance in a series circuit is...
just the sum of each component.
6
New cards
R= R1 + R2 + R3
7
New cards
Voltage in a parallel circuit is...
the same across each path.
8
New cards
V1 = V2 = V3
9
New cards
Current in a parallel circuit is...
shared across all components, proportional to their resistance. DO THE RATIO - more current will go across less resistance.
10
New cards
Resistance in a parallel circuit is...
lower, because the charge has more branches to flow across. The more branches you add, the less the total resistance is. It can be calculated using 1/R = 1/R1 + 1/R2.
