Does an Ohmeter that has an infinite reading indicates an open circuit?

Yes, or a circuit with a resistance higher than the capability of the meter, which would be unusual.

How much current flows in a circuit with an open circuit?
None.AnswerIt depends! A capacitor is an open circuit, yet a.c. current flows quite readily. And d.c. current will flow for a very short period of time.
What if your reading material mentions switches fuses and circuit breakers as three of the most important devices for?
cutting off or isolating an electrical circuit
What does Barometric reading falling mean?
Falling barometric pressure usually indicates wet weather is on the way.
What does it mean if the barometer reading is falling?
A falling barometer reading typically indicates that low pressure and unsettled weather is approaching. This can often signal the arrival of stormy or rainy conditions.
What tool can be used to test for electrical conductivity?
A multimeter can be used to test for electrical conductivity. By setting the multimeter to the resistance mode, you can measure the resistance across a material or circuit to determine its conductivity.
When you connect a multimeter across an open component what is the reading?
When a multimeter is connected across an open component, the multimeter will display an infinite or overload reading. This indicates that there is no electrical continuity or path for current flow through the component, as it is disconnected or broken.
A zero reading on an ohmmeter means the circuit or component is open is this true or false?
This is false. A zero reading is what you get when you press the probes of themeter together with nothing between them, to make sure the meter is working.That's about as closed as the circuit under test can get.
How do you find out the un known resistance value?
1.Use of ohmeter. Connect the ohmeter terminals to the the ends of the unkown resistance and take the reading. Adjust the range to give a good accuracy. 2. Use of colour codes. This applies if the unknown resistance is of a resistor with visible colour codes on it.
How do you test a horn relay in a 1993 Plymouth Sundance where the relay clicks when button is pressed but horn doesn't sound?
Relays can be a pain sometimes. There are two acceptible methods for checking relays ( that you can do at home anyway) the first and easiest is to simply swap it with a known good relay of the same specs. if this is not possible then the only other way is with an ohmeter ( a quality multitester is a must have for any do it yourselfer). compare the suspect relay to it's connector there should be four wires, two thin (control circuit) and two thick (power circuit). you need to connect your ohmeter across the power circuit. and connect a jumper wire to each control circuit terminal. connect one jumper to the ground post on your vehicles battery and touch the other to the positive for no more two seconds at a time while watching your ohmeter. If the relay is working properly you should have less then one ohm showing. if the reading is high, or the tool does nothing, you've found you're problem, otherwise, start following wires and checking for voltage, or check the whole system by jumping the power circuit. check the control circuit with an ohmeter, turn the switch on with battery disconnected and key in run position and check ohms across the relays empty connector, more than 2 ohms means a short or bad connection. good luck and be careful out there eh.. PS... use a stick or something between the horn and seat to keep the switch closed while you check the control circuit ( one person can bleed brake systems with this technique).
What is the maximum insulation resistance reading on a 800A busbar?
infinite
What if you have a negative kvar reading?
A negative KVAR reading can be eliminated by adding an inductor to the circuit.
What happens to the ammeter reading if resistor is removed?
If the resistor is removed from the circuit, the total resistance in the circuit decreases. This causes the total current in the circuit to increase, which would result in an increase in the ammeter reading.
How do you find the proper circuit breaker for an air conditioning unit?
By reading the manual cocerning circuit amperage
What does a ampermetre do in a circuit?
Spelt: AmmeterIt measures the current flowing around the circuit. In different places in the circuit, the reading may be higher or lower.
Can an ohmeter measure the value of a resistor when it's already in the circuit?
It can be difficult to directly measure a resistance while it is in circuit. Generally, other parts of the circuit will have an effect on the readings an lead to errors that are difficult to predict. If the other parts of the circuit are understood, it may be possible to calculate the total theoretical resistance from the component values and then compare it to an actual reading. This is often unreliable because it doesn't prove that a specific resistor is a certain value. It is almost always better to power the circuit and use a voltmeter to establish the voltages at different points in the circuit. If the circuit is understood, voltage readings can often show faults in resistors or other components very quickly. Alternatively, voltage readings can be used to ascertain a resistance value if it isn't marked. Whatever the task, there is always an amount of detective work and the route to take depends very much on the circuit, hence there are no specific examples mentioned here.
Reading of a odometer is a vector or scalar?
It's a scalar. It indicates distance but not direction.
