Unit 10A Review

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts (V). It represents the energy per unit charge available to move electrons through a circuit.

Front

Does voltage depend on the devices within a circuit?

Back

No, voltage does not depend on the devices within a circuit. It remains constant regardless of the number of devices added.

Front

What is a battery?

Back

A battery is a power source that converts chemical energy into electrical energy, providing the necessary voltage to drive current through a circuit.

Front

What is a closed circuit?

Back

A closed circuit is an electric circuit that has no breaks, allowing electric charge to flow continuously.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A). It represents the rate at which charge is flowing.

Front

What is an open circuit?

Back

An open circuit is a circuit that has a break or gap, preventing the flow of electric charge.

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω). It determines how much current will flow for a given voltage.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It can be expressed as V = I × R.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points or junctions, allowing multiple paths for current to flow.
