Multimeters.
The four types of measurement meters
What is ohmmeter,ammeter,voltmeter and DMM
Three types of circuits
What is Series, Parallel, and combination?
What are the 3 basic electrical measurments
Voltage, Resistance, and Current
What is the symbol for Megaohms?
MΩ
How do you measure voltage?
Set the Black lead to COM (common) and the red lead to Voltage. Then measure circuit.
Differences between analog and Digital meters
Analog has greater inaccuracy, worse ease of readability, and a pointer.
Digital has greater accuracy, and ease of readability, and shows negative when polarity is reversed.
How does the current flow in a series circuit
Through everysingle component in the circuit
How do you find voltage
Amps*Ohms
What is the symbol for Kilohms?
KΩ
How to measure resistance
Set black lead to COM (common) then red lead to resistance. Then dissconnect a resistor, and measure the reistor.
DMMs measure multiple values, what are they?
What is Ohms, Amps, Volts, Watts
How does current flow through a parallel circuit
The flow of current is divded among the resistance
How do you calculate Ohms
Voltage/Amps
What is the symbol for milliamps?
mA
How to measure continuity.
Connect black to COM (common) and red lead to continuity, then cut the wire, then mesure. If there is continuity it would beep, no continuity, no beep.
How do you use a multimeter?
What is plug-in probes, set finding value (ohms, amps, current, volts,) set probes between positive and negative points, and read value?
What are the main parts of a circuit
A cell, wires, a switch, a output device
How do you calculate Amps
Watts/Volts
What is the symbol for microamps?
How to measure AC current?
Plug black lead into COM(common) then red lead into AC, Then plug black into the negitive part of the outlet, and the red into the positive. If reversed will cause a short.
