Electricity (Honors)

Front

What is the function of a switch in an electrical circuit?

Back

When a switch is closed, it completes a circuit.

Front

Which component in a circuit is a resistor?

Back

The light bulb.

Front

What does Ohm's Law state about current, voltage, and resistance?

Back

Current is equal to voltage divided by resistance (I = V/R).

Front

How can you increase the current in a circuit with a motor that requires 3 amps?

Back

Increase the voltage of the circuit by using a 6 volt battery.

Front

What is the relationship between voltage, current, and resistance according to Ohm's Law?

Back

Current is directly proportional to voltage and indirectly proportional to resistance.

Front

Define voltage in an electrical circuit.

Back

Voltage is the electric potential difference between two points in a circuit.

Front

What is current in an electrical circuit?

Back

Current is the flow of electric charge, measured in amperes (A).

Front

What is resistance in an electrical circuit?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is the formula for calculating voltage?

Back

V = I × R (Voltage = Current × Resistance).

Front

What is the formula for calculating current?

Back

I = V / R (Current = Voltage / Resistance).
