Electricity Physics Quiz for Class 10 Students

What is the unit of electric current?

What is the SI unit of electric charge?

What is the relationship between voltage, current, and resistance in a circuit?

What is the SI unit of electric potential difference?

What happens to the resistance in a conductor when its temperature increases?

What is the direction of conventional current flow in an electric circuit?

Electric Current and Charge

Electric current is measured in amperes (A), which represent the flow of electric charge.
The SI unit of electric charge is the coulomb (C), defined as the amount of charge transported by a constant current of one ampere in one second.

Voltage, Current, and Resistance

The relationship between voltage (V), current (I), and resistance (R) in a circuit is described by Ohm's Law: ( V = I \times R ).
This equation indicates that voltage is directly proportional to the product of current and resistance.

Electric Potential Difference

The SI unit of electric potential difference, or voltage, is also the volt (V), equivalent to one joule per coulomb.

Resistance and Temperature

As temperature increases, the resistance of most conductors, like metals, typically increases due to increased atomic vibrations that impede electron flow.

Conventional Current Flow

Conventional current flow is defined as the flow of positive charge, moving from the positive to the negative terminal of a power source, even though electron flow is opposite.
