Question 1 of 10
What is the primary function of voltage in an electrical circuit?
Voltage is the electrical potential difference that causes current to flow.
Question 2 of 10
What is the unit of voltage?
The unit of voltage is the Volt (V), named after Alessandro Volta.
Question 3 of 10
Which of the following is also known as electromotive force (EMF)?
Voltage and EMF are often used interchangeably to describe the potential difference that drives current.
Question 4 of 10
What happens to the current flow if the voltage in a circuit is increased?
Increasing the voltage provides a greater force to drive the current, thus increasing the current flow (assuming resistance remains constant).
Question 5 of 10
Which of the following is a common DC voltage level?
12V is a common DC voltage level used in various applications like car batteries.
Question 6 of 10
What type of charge do electrons carry?
Electrons carry a negative charge.
Question 7 of 10
Which of the following describes the relationship between voltage and current?
According to Ohm's Law (V=IR), voltage and current are directly proportional when resistance is constant.
Question 8 of 10
What is the term for the potential difference between two points in a circuit?
Voltage is defined as the potential difference between two points.
Question 9 of 10
If a device is designed for 220V, what will likely happen if it's connected to a 12V supply?
The device designed for 220V will not function and can get damaged if connected to a lower voltage (like 12V).
Question 10 of 10
In the water analogy, what represents voltage?
The water level in the tank represents voltage, as it provides the pressure to drive the water flow.
