Term
 Series circuit
Definition
 I is constant; 1/Ceq= 1/c1 + 1/c2; Veq = V1+V2; Q=VC; V=IR; Req=R1 + R2; P=I^2 xR
Term
 Parallel circuit
Definition
 V is constant; Ceq = C1+C2; Ieq=I1+I2; 1/Req = 1/R1 + 1/R2; Q=VC; V= IR; P = V^2/R
Term
 Kirchoff's Rules
Definition
 Sum of potential charges along a closed circuit is zero; sum of currents entering a junction point is equal to the currents leaving it
Term
 Kirchoff's guidelines- V and R
Definition
 V: lower to higher potential = +E; higher to lower potential = -E; Going across resistor in the same direction as the current: -iR; going across resistor in opposite direction of current: +iR
Term
 Series, Parallel light bulbs
Definition
 if two bulbs share the same current, the bulb which has a lower voltage drop is dimmer.if two bulbs share the same potential, the bulb which draws the lesser amount of current is dimmer.
Term
 light bulbs
Definition
 If a 100 watt bulb and a 60 watt bulb are in series with each other, they share the same current. Since the 100 watt bulb has a thicker filament, which has less resistance, it will glow dimmer than the 40 watt bulb which has a thinner, higher resistance filament.If a 100 watt bulb and a 60 watt bulb are in parallel with each other, they share the same voltage. Since the 100 watt bulb has a thicker filament, which has less resistance, it will draw more current and glow brighter than the 60 watt bulb which has a thinner, higher resistance filament.
