Assignment 19: DC Circuits
Basic DC Circuit
Battery
resistor
connecting wires
current time graph
flat line (constant current)
X axis: time (t)
Y axis: current (I)
Current Flow
conventional current (I)
flows from positive to negative
Electron flow
flows from negative to positive
Measuring Current
Ammeter diagram
symbol: circle with an A inside
circuit with ammeter
ammeter connected in a series with a resistor
Water flow analogy
water flow system diagram
pump = battery
narrow pipe = resistor
flow = current
comparison
water pressure = voltage
flow rate = current
pipe resistance = electrical resistance
Parallel circuit - potential
multiple paths
one with potential rise (across battery)
one with potential drop (across resistor)
shows voltmeter across components
arrows for current direction
