When using the ohmmeter function of the digital multimeter to check continuity, what does the "ol" in the display mean?

Answers

Ask one question at a time, it's so annoying looking for an answer and finding someone that wrote the whole test and anyway no one will answer all

1. To get the total resistance in a series circuit, all you need to do is add the resistance in each resistor. 

The answer is C.  

2. The unit of electricity that does the work in a circuit is the current and the unit of current is Ampere or A. Ampere is the flow of one coulomb per second. 

The answer is D.

3. The Basic Parts of an Electric Circuit is an energy or power source, a conducting wire, electrical load or a device and a controller or a switch. A fuse can be included for protection. 

The answer is D. 

4. Kilo means 1,000. Like in kilograms, the base unit is grams and kilo means thousand, so in short it is a thousand grams. So if a meter shows 0.75 kiloohms then you multiply that by a thousand and you will get 750 ohms. 

The answer is A.

5. A voltmeter is used to check for variable voltage output from an ignition sensor or computer. It measures the electrical potential difference between two points in a circuit. An analog meter is too general, a continuity light measures current flow and a logic probe analyzes logical states.

The answer is B.

6. The lines on an oscilloscope display are called a graticule. It is a type of electronic test instrument that is used to observe changes in an electrical signal over a period of time. The voltage and time shows a shape that is continually graphed based on a calibrated scale. 

The answer is C.

7. Silver is actually the best conductor of electricity but it is very expensive and is not often used. If we look at your choices, the next best conductor would be copper. It is more commonly used because it is a lot cheaper. 

The answer is C.

8. An antistatic sprat is a used to eliminate static electricity. It prevents static cling and not used to locate a short circuit. It is commonly used on clothes. It cannot be used on some electrical equipment like monitor screens.

The answer is B. 

9. As temperature increases, the conductor increases in resistance. This is because the free electrons and the captive ones collide more as the temperature increases. 

The answer to your question is C.

10. Without the illustration, we cannot answer this question.

11. It is true that current takes the path of least resistance, especially in a series circuit. However, current takes all paths available. If you look at a parallel circuit, the wiring is not in a continuous line but the current flows through all resistors that are in the circuit, unless the impedance is not greater than the current flowing.

The answer is D.

12. An analog scope uses a cathode ray tube (CRT) not an LCD display. The CRT is used to display the voltage patterns. This means that Technician A is incorrect. So you are left with Technician B.

The answer is A. 

13. Milli means 1/1000. If the value is millivolt then that means that there are one thousandths of a volt. So if we convert your figure from 432 millivolts to volts, then we divide the value by 1000. The answer is then 0.432 volts.

The answer is C.  

14. In a series circuit, the sum of the voltage drop should be equal to the applied voltage. The same current flows in each resistor and the part of the source voltage drops across each resistor. The total resistance in a series circuit is the sum of all the resistors in the circuit.

The answer is then A.

It usually stands for open loop, another way of saying there isn't continuity.

or  it can also means OVER-LIMIT

beyond the limits of the meter to register, such as "infinity" on a resistance scale

which are both the same thing
