In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?
Somebody is trying a trick question! The electron that comes out of the negative terminal has zero potential energy. With respect to the positive terminal it has -1.5V of electrical potential energy, and so does every other electron at 0.0V whether or not they came out of the battery.
What direction do the electrical charges flow?
Electrical charges flow from areas of higher potential (voltage) to areas of lower potential. This means that they flow from the positive terminal of a battery to the negative terminal in a closed circuit.
How do you induce polarity in galvanometer?
To induce polarity in a galvanometer, you can connect the positive terminal of a power source to one terminal and the negative terminal to the other terminal. This creates a potential difference across the terminals of the galvanometer, inducing polarity in the device.
Can terminal potential difference be greater than the emf supplied?
No, the terminal potential difference cannot be greater than the emf supplied. The emf represents the maximum potential difference that the cell or battery can provide, while the terminal potential difference is the actual potential difference across the terminals when a load is connected.
WHAT PUSHES THE ELECTRONS TO FLOW?
Electrons flow in a circuit due to the electric potential difference, or voltage, between two points. This voltage creates an electric field that exerts a force on the electrons, causing them to move from a higher potential (positive terminal) to a lower potential (negative terminal).
When an action potential reaches an axon terminal, what happens to the neurotransmitters?
When an action potential reaches an axon terminal, it triggers the release of neurotransmitters into the synaptic cleft.
When an action potential reaches the nerve terminal, what happens to the neurotransmitter release?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".

The terminals of a diode are called the?
anode positive potential cathode negative potential
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
What happens when an action potential reaches the nerve terminal?
When an action potential reaches the nerve terminal, it triggers the release of neurotransmitters into the synapse, which then transmit signals to the next neuron or target cell.
What happens when the action potential reaches the axon terminal"?
When the action potential reaches the axon terminal, it triggers the release of neurotransmitters into the synapse, which then bind to receptors on the neighboring neuron, continuing the signal transmission.
What is it when too much current flows through a conductor?
Overcurrent, sometimes called shortcircuit.
What direction do the electrical charges flow?
Electrical charges flow from areas of higher potential (voltage) to areas of lower potential. This means that they flow from the positive terminal of a battery to the negative terminal in a closed circuit.
