1. Ohm's law: V=IR
2. Circuit is called a circuit because (circle) it is a closed loop in which charges can flow through
3. Resistance = 1V/1A
Next we moved onto our lab in which we built parallel and series circuits by ourselves.
Rules:
1. Everywhere along a wire has the same voltage
2. Voltage does not occur only across resistors.
Positive current flows from high V to low V
3. Current is conserved (total charge in = total charge out)
Analysis:
Series circuit: The total resistance = the sum of all resistances. Also, the current remains the same while the voltage drop differs
Parallel circuit: The total resistance = The sum of both halves (or more) of the circuit. The current is different in different areas while the voltage drop is the same.
Real World Connection:
Depending on its use, any house or electronic device could be built with different circuitry to fit the user's various energy needs whether he prefers a higher voltage or better resistance.
