When the terminals are connected in the circuit
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
A negative feedback will stabilize an amplifiers positive feed back will force the amplifier to either saturated state. this will hold true for a system too. A more general answer follows. 1. Feedback: Getting information about what just happened and responding to it. 2. Negative Feedback: The response lessens the output. 3. Positive Feedback: The response increases the output.
positive feedback
The reaction is spontaneous.
In the ONPG test, organisms may be positive due to the presence of beta-galactosidase enzyme, which cleaves ONPG and produces a yellow color. However, in the lactose fermentation test, some organisms may lack other necessary enzymes or transport systems to fully metabolize lactose, resulting in a negative result despite having beta-galactosidase.
Yeah
When an electric device is connected to a battery, an electric current is produced due to the difference in potential between the positive and negative terminals of the battery. This potential difference, also known as voltage, creates an electrical force that pushes the flow of electric charge (current) through the circuit and powers the device.

Because when there is a positive and a negative in the same problem, it gives you a negative. An easy way to solve problems like that is if there is an odd number of negative signs, then your answer is going to be negative. If there is an even number of negative signs, then your answer is going to be positive. (no matter if there is a positive sign in a math problem).
When an electric field separates positive and negative charges, it produces an electric potential difference between the charges. This results in the positive charges accumulating on one side and the negative charges accumulating on the other side, creating an overall charge separation.
The anode produces positive charges, while the cathode produces negative charges.
A factor is a number or quantity that when multiplied with another produces a given number or expression. A positive factor is a factor that is positive, as opposed to negative.
You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.
The battery produces a voltage; if a conducting wire - or any circuit for that matter - is connected, a current will flow according to Ohm's Law, that is, the current is calculated as voltage / resistance.
A factor is a number or quantity that when multiplied with another produces a given number or expression. A positive factor is a factor that is positive as opposed to being negative.
