Electronic Circuits In General
Closed loop
Electrons flow from negative terminal to positive terminal.
Current, voltage, resistance, power (E/IR)
Voltage (Volts) E = I R
Current (Amps) I = E / R
Resistance (Ohms) R = E / I
Power (Watts) P = I * E = I
2
* R = E
2
/ R
Similar to current, pressure, resistance in water/air circuit
Electronic components will alter the flow of current in the circuit.
Parallel vs. series circuits
Kirchoff's law(?) - the sum of the currents flowing into a junction equal the sum of the currents flowing out of a junction.
Sum of the voltage drops around a circuit equals the source voltage
