Ohm's law |
Current is directly proportional to voltage and inversly proportional to resistance. |
|
|
|
Current |
The flow of electrons. Measured in amperes. Directly proportional to V. |
|
|
|
Power |
Rate of work being done by electricity in a circuit. Measured in watts. Directly proportional to I & V. |
|
|
|
3 formulas of Ohm's law |
I=V/R. R=V/I. V=IR. |
V is always on top of equation |
|
|
Voltage |
Electrical pressure/force that makes current flow. Measured in volts. |
|
|
|
Series Circuit |
Circuit where the current flows in a single path through ALL components. Voltage is additive, current is constant. |
|
|
|
Current flow |
From negative/ground to positive |
|
|
|
Total resistance(series) |
Equals the sum of all resistors in the circuit. |
|
|
|
Voltage drop |
When Current flows through a resistor, voltage is developed across the resistor. Vr= It*R(of specific resistor) |
|
|
|
Troubleshooting procedure |
1. Analyz the circuit 2. Check the set up 3. Calculate and measure 4. Check results |
|
|
|
Series circuit opens |
Occurs when a component provides no path for current flow. Entire Va will be read on multimeter across the open component. |
|
|
|
Series Circuit short |
Occurs when a component provides no resistance to current flow. Vr across shorted component reads 0. |
|
|
|
Changed value |
Occurs when a components resistance value increases or decreases, causing voltage to change inversely. |
