D.C. circuits Flashcards
What is a series circuit
A series circuit is a circuit that has only 1 path for which current can flow, so the current passing through every component in the circuit is the same
What is a parallel circuit
Parallel circuit is a circuit that has more than 1 path in which current can flow so total current equals to sum of individual currents in each branch
Define effective resistance
Effective resistance is the combined resistance of all the resistors in a circuit
Define a bypass circuit
A bypass circuit has an alternative path of zero resistance for current to flow
Define a short circuit
A short circuit is an unintentional bypass in circuit or bypass of power source, resulting in a very large current
How does resistance of light-dependent resistor change
- Brightness decreases
- Resistance increases
How does resistance of thermistor change
- Temperature decreases
- Resistance increases
