Unit 7 Test - Electrostatic and Electrical Energy

Front

What is electrostatic force?

Back

The force between charged objects, which can be attractive or repulsive depending on the nature of the charges.

Front

What happens to the electrostatic force if the distance between two charged objects is halved?

Back

The electrostatic force increases by a factor of four, according to Coulomb's Law.

Front

What is the formula for calculating current in a circuit?

Back

Current (I) = Voltage (V) / Resistance (R) according to Ohm's Law.

Front

If the resistance in a circuit is tripled, what happens to the current?

Back

The current decreases to one-third of its original value.

Front

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

Back

Voltage is directly proportional to current when resistance is constant.

Front

Define electric charge.

Back

A property of matter that causes it to experience a force when placed in an electromagnetic field; it can be positive or negative.

Front

What is the unit of electric charge?

Back

Coulomb (C).

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.

Front

What is the effect of increasing voltage on current in a circuit with constant resistance?

Back

Increasing voltage increases current.

Front

What is the effect of decreasing voltage on current in a circuit with constant resistance?

Back

Decreasing voltage decreases current.
