E TEST- Analyzing Parallel Circuits
Parallel circuit
circuit that connects to two or more components so there is more than one path for the current
Resistors in parallel
have the same potential difference across them, (they see the same voltage)
Equivalent resistors in parallel cicuits
all resistors can be combined into one smaller resistor
what is the sum of yhe current across each resistor equal to?
the total current across the parallel resistors
what happens if one component of a parallel circuit burns out?
the remaining components still work
Steps for solving Parallel circuits: Step 1
Find the RE of the circuit- 1/RE= 1/R1+1/R2+1/R3+...
Steps for solving Parallel circuits: Step 2
find the voltage across a battery or any of the resistors (they are all the same)- IB RE =I1 R2 = I2 R2 + I3 R3
Steps for solving Parallel circuits: Step 3
Find the current across each resistor - I1 = (theta)V / R1, I2 = (theta)V / R2...
