In an electric potential graph, what does a positive jump indicate?
A positive jump indicates a voltage gain, typically from a battery.
In an electric potential graph, what does a negative slope indicate?
A negative slope indicates a voltage drop, typically across a resistor.
What does the height of an electric potential graph represent?
The height represents the electric potential at a specific point in the circuit.
What does a flat line in an electric potential graph indicate?
A flat line indicates a region of constant electric potential with no voltage change.
In an electric potential graph, what does a steep slope indicate?
A steep slope indicates a large voltage drop over a short distance, often associated with a high resistance.
Label the electric potential graph showing voltage drop across a resistor.
1: Initial Potential, 2: Voltage Drop, 3: Final Potential, 4: Resistor.
What is the effect of increasing the resistance in a circuit loop?
For a given voltage source, increasing resistance will decrease the current flowing in the loop.
What is the effect of increasing the voltage of a battery in a circuit loop?
Increasing the battery voltage will increase the current flowing in the loop, assuming resistance remains constant.
What happens if the sum of voltage changes around a closed loop is not zero?
This violates the principle of energy conservation, indicating an error in the circuit analysis or an impossible circuit configuration.
What is the effect of traversing a resistor in the direction of current flow?
It results in a voltage drop, meaning the electric potential decreases.
What is the effect of traversing a battery from its negative to positive terminal?
It results in a voltage gain, meaning the electric potential increases.
