Electricity
These are basic units of Resistance and Current
What is Ohm and Ampere?
This component supplies the energy to create and electrical current
What is a Power Supply?
The formula for OHMS Law
What is E = I x R
This happens to a flow when resistance increases in a circuit
Current Decreases
A circuit protection device that trips and can be reset
What is a circuit breaker?
The amount of cycles in AC electricity in the U.S.
What is 60 cycles (or hertz) per second?
What is a Motor?
The amount of electromotive force produced on a circuit with a 10 OHM resistor with 2 Amp flowing through
What is 20 volts?
This is why AC power is used for long distance transmission
What is easier voltage transformation and lower losses?
This condition occurs when an extra pathway with almost no resistance is in the circuit
What is a short circuit?
This switch is frequently used for start and stop operations
What is a pushbutton switch?
The term for the flow of electrons through a circuit
What is Current?
The amount of current in a 120V series circuit with a 15 ohm and 10 ohm resistor
What is 3 amps?
The unit used to measure electrical power
What is a Watt?
This is the reason a lightbulb produces light
What is an electrical energy converted into light and heat?
This energy is the existence of a potential difference between two points in a circuit
What is Electromotive Force or Voltage?
What is the ability of a component to store an electrical charge?
What is Capacitance?
This German physicist determined two laws in 1845. One was his Current law and this other one. We are looking for the name of the law and the equation
Kirchoff’s Voltage Law. The total voltage in a series circuit is equal to the sum of the individual voltage drops in the circuit. (V total = V1 + V2 etc)
If a circuit’s resistance is cut in half while the voltage stays the same what happens to the power?
What is power doubles?
This is why parallel circuits are used in household operations
What is independent operations of load?
This term signifies how much power a circuit will draw
What is resistance?
This device is a handheld diagnostic tool for measuring electrical values
What is a multimeter?
This formula determines resistance in a parallel circuit. Give me whole formula
What is 1/total resistance is equal to 1/resistor one plus 1/ resistor two etc?
In this this first circuit type, a short can cause all current to bypass the load entirely, while in the other second type, a short typically affects only one branch but can still increase total current draw significantly
What is series then parallel?
The main purpose of a relay in control circuits
What is switching a higher power load using a low power signal?
