2. Series Circuit
• One pathway (circuit)
• Current (flow of
electric charge) same
anywhere in the
circuit
• Voltage (measure of
strength of electrical
power) shared in ratio
to resistance
Parallel Circuit
• Two or more pathways
• Current splits, passes
through pathways, and
adds up again
• Voltage across each
pathway equals supply
voltage
3. Series Circuit
• Resistance (reduction
of electrical current)
adds up, draws less
current = battery
(power source) lasts
longer
Parallel Circuit
• Total resistance less
than the least
resistance, current
drawn is less
= battery life short
4. Series Circuit
• One bulb (load) fuses,
circuit incomplete
(open or broken)
• Brightness of bulbs
less because P = IV
P (Power), I (Current), V (Voltage)
Parallel Circuit
• One bulb fuses, the
others will still work
• Brightness of bulbs
more
