T
time constant units
_____ difference cross each parallel resistor is ____ to the potential of that branch:
Potential; equal
V(par)= V1= V2= ..
______through each parallel resistor _____ to the total current entering that branch
Current; adds
Itot(par) = I1+ I2+ ...
Equivalent resistance _____ 2 or more original resistors
Replaces
In ____, 2 or more resistors are connected end-to-end with no _______in-between.
series, junction
Potentials add:
-Same as capacitors
-ΔVtot(ser)= ΔV1+ ΔV2+ ...
-ΔV = I R1+ I R2= I (R1+R2)
_____ is ____ in all resistors:▪Any charge that flows through one resistor must flow through the others
*Similar to series capacitors: Qser= Q1= Q2= ...
Currents;equal
Junction Rule
the sum of all currents entering a junction must equal the sum of the currents leaving (conservation of charge)
Loop Rule
The sum of the potential differences across all circuit elements around any closed loop must be zero.
V = -IR
V = +IR
The resistor is analyzed in the direction of the current, the potential across the resistor
The resistor is analyzed in the opposite direction of the current, the potential across the resistor
The emf source is analyzed in the direction of ______ voltage (from + to -terminals), the change in the electric potential is
decreasing
V = -ε
The emf source is analyzed in the direction of ______ voltage (from -to + terminals), the change in the electric potential is:
increasing
V = +ε
Charge on the capacitor_____ exponentially with time:
increase
Current in a charging RC circuit ____ exponentially with time
decreases
T depends on both
R and C
The degree of damage depends on
1)Current: the magnitude; how much
2)Time: how long current is present
3)Body part:where you get shocked
