Yes, but it is not very useful in open loop mode. In open loop mode, unless you happen to be very lucky (as in extraordinarily lucky, meaning you won't be) the output will be pegged to one of the two rails. The op-amp will be operating in saturated mode instead of linear mode, and its response time will suffer. You could also damage the op-amp.

What is the difference between open loop and closed loop gains of an op amp?
A: Usually by looking at the specification for that op-amp and there will be accuracy deviation from device to device. To use it open loop is practically impossible all it tells from specification that there will be enough gain when the loop is closed and the max frequency available
Why voltage gain is high in op amp?
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
What are the ideal op-amp approximations?
Ideal op amp approximations: -no current goes into the positive or negative input of the op amp. -The open loop gain is infinite. -Voltage at positive input is the same as the negative input.
What is the effect of the op amp in the circuit?
So long as you remain with the range of the device (power supply rails less a volt or two), the output of an op-amp will go to what ever value is required to maintain the input stages (bridge) to remain the same. So, the effect on input voltage on output of an op-amp is dependent on the feedback circuit.
What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
Why open loop gain of op-amp is very high?
A; An ideal op amp should have infinite open loop gain so when the loop is closed with negative feedback it will be stable
What is the difference between open loop and closed loop gains of an op amp?

Is it possible for an amp to go into protection mode from overheating?
yes...yes it is
Does an open loop gain of an op-amp change with a variation of the resistors and transistors inside the IC?
It could do, which is why an op-amp is made with a very high open-loop gain so that the actual gain can be closely controlled by the passive feedback components.
What are the ideal op-amp approximations?
Ideal op amp approximations: -no current goes into the positive or negative input of the op amp. -The open loop gain is infinite. -Voltage at positive input is the same as the negative input.
What is the approximate gain of an op-amp open loop?
It is between 100,000 and 1,000,000 and even more. In dB, it is between 100dB to 120dB.
Which line 6 amp has a effects loop?
Line 6 Jam amp
How can I incorporate an effects loop into my amp if it does not already have one?
To incorporate an effects loop into your amp if it does not already have one, you can consult a professional technician or purchase an external effects loop pedal that can be connected between your guitar and the amp. This will allow you to add effects pedals into the signal chain without altering the amp itself.
Why does the amp make noise when you get too close?
It's called feedback. The microphone causes a loop, what is coming out if the amp is being asorbed by the mic, sent back to the amp and projected again. The loop causes a squeal.
Stability range of an ideal op amp?
A; the stability is a function of gain assuming perfect matched input the range can be from a gain of practically Nil to close to open loop configuration
What makes closed-loop op amp unstable?
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
