Total questions: 10
Worksheet time: 8mins
Series circuits have:
Same voltage
Same current
Same power
Same resistance
Parallel circuits have:
Same voltage
Same current
Same power
Same energy
Total resistance in parallel is:
R1+R2
R1×R2
Less than the smallest resistor
Greater than all
If one branch in parallel opens, current:
Goes to zero
Flows in remaining branches
Increases in all
None
Voltage drop in series depends on:
Current only
Resistance only
Both I & R
Power
Kirchhoff's Current Law states:
Voltage sum = zero
Current entering = current leaving
Power is constant
Resistance is constant
A parallel circuit with many branches has:
Higher current demand
Lower current demand
Higher resistance
Zero current
In series, total voltage is:
Divided
Constant
Multiplied
Zero
The main advantage of parallel circuits is:
Lower cost
Independent branches
More heat
More resistance
A blown bulb in series causes:
All bulbs off
All bulbs dim
All bulbs brighter
No change
