Combo Meal
A point in a circuit where one path for current splits into two or more paths.
What is a node?
The magnetic field a coil of wire generates is proportional to this.
What are ampere-turns?
The algebraic sum of voltage sources and voltage drops in a series circuit must equal zero.
What is Kirchoff's voltage law?
This type of meter has its own power source.
What is an Ohmmeter?
Opposition to current flow.
What are Ohms?
This is how resistances connected in parallel are added together.
What is reciprocally?
This electromagnetic coil converts electrical energy into mechanical movement.
What is a solenoid?
The algebraic sum of the currents entering and leaving a point must equal zero.
What is Kirchoff's current law?
This type of meter has a high resistance and is connected in parallel to what it is measuring.
What is a voltmeter?
Electromotive force
What are Volts?
This will be equal for two or more resistors connected in series.
What is current flow?
Dividing the amount of inductance by the amount of resistance in a DC circuit gives us this value.
What is Tau or the R/L time constant?
His law defined the polarity of induced voltage in a coil.
Who is Lenz?
These are resistors connected in series with the meter movement to allow multiple voltage ranges to be measured by a DC analog voltmeter.
What are multipliers?
The rate energy is consumed
What are Watts?
This can be calculated in the same way for series, parallel or combination circuits.
What is total circuit power?
This will oppose applied voltage and changes in current in an inductive DC circuit.
What is induced voltage?
His law stated that the amount of voltage induced in a coil is directly proportional to the rate of change in a magnetic field and the number of turns of wire in the coil.
Who is Faraday?
An analog ammeter requires this low resistance component to protect the meter movement.
What is a shunt?
Coulombs per second
What are Amps?
This will be equal for two resistors connected in parallel.
What is voltage drop.
The inductance of a coil is inversely proportional to this.
What is the length of the core?
The amount of current in a circuit is directly proportional voltage and inversely proportional to resistance.
What is Ohm's law?
This is the base instrument used in devices for measuring electrical quantities.
What is a galvanometer?
The Inductance of a coil
What are Henrys?
