[Electrical Circuits/Multimeters] Flashcards
What is any device through which an electrical current flows and which changes electrical energy into a more useful form of energy?
Load
What is the device that furnishes the electrical energy used by the load?
Source
What permits control of the electrical device by interrupting the current delivered to the load?
Switch
What is an engineer’s main aid in troubleshooting a circuit in a piece of equipment?
Schematic diagram
What states: “The current in a circuit is directly proportional to the applied voltage and inversely proportional to the circuit resistance?”
Ohm’s Law
What is the rate at which work is being done?
Power
What is an electrical force that forces current to flow in a closed circuit?
Voltage
What is the instantaneous rate at which work is done?
Electric power rate (P) watts
What is a complete conducting pathway?
Electric circuit
What is a circuit that contains only one path for current flow?
Series circuit
What is it called when loads in a circuit consume voltage (energy)?
Voltage drop
What determines the value of the voltage dropped by a resistor?
Applied voltage
What states: “The algebraic sum of the voltage drops in any closed path in a circuit and the EMFs in that path is equal to zero.”
Kirchhoff’s Law
What occurs when a break interrupts a complete conducting pathway?
Open circuit
What is an accidental path of low resistance that passes an abnormally high amount of current?
Short circuit
