What is electric potential difference?
Click to flip
Electric potential difference is the work done in moving a unit charge from one point to another in an electric field.
Click to flip
What is the formula for electric potential difference?
Click to flip
The formula is V = W/Q, where V is the potential difference, W is work done, and Q is charge.
Click to flip
In what units is electric potential difference measured?
Click to flip
Electric potential difference is measured in volts (V).
Click to flip
Why is electric potential difference important in circuits?
Click to flip
It drives the flow of electrons and determines how much work can be done by the electrical charges.
Click to flip
What instrument measures electric potential difference?
Click to flip
A voltmeter measures electric potential difference.
Click to flip
How does resistance affect electric potential difference?
Click to flip
Higher resistance reduces current for a given potential difference, according to Ohm's Law.
Click to flip
What is the relationship between electric potential difference and energy?
Click to flip
Electric potential difference is proportional to the energy transferred per unit charge.
Click to flip
Can electric potential difference be negative?
Click to flip
Yes, if point B is at a lower potential than point A, the potential difference (VBA) is negative.
Click to flip
What factors influence electric potential difference in a circuit?
Click to flip
Factors include the amount of charge, resistance, and the arrangement of components.
Click to flip
How does electric potential difference relate to power?
Click to flip
Power (P) is the product of electric potential difference (V) and current (I), expressed as P = VI.
Click to flip
What is the zero potential reference point usually in circuits?
Click to flip
The ground (Earth) is often considered the zero potential reference point.
Click to flip
How can electric potential difference be increased in a circuit?
Click to flip
By increasing the battery voltage or reducing the circuit's overall resistance.
Click to flip
Does electric potential difference change over a resistor?
Click to flip
Yes, potential difference drops across a resistor, converting electrical energy into other forms like heat.
Click to flip
What is a practical example of electric potential difference?
Click to flip
Batteries supply a constant electric potential difference to power electronic devices.
Click to flip
Can electric potential difference exist without a circuit?
Click to flip
Yes, a potential difference can exist without a full circuit, but no current flows without a closed path.
