Circuits (Unit 6)

Front

What happens to current when a switch is open?

Back

Current will stop flowing.

Front

What happens to current in a circuit as resistance increases?

Back

Current will decrease.

Front

What is a circuit that only has ONE path for electricity to flow?

Back

A series circuit.

Front

What is the total resistance in a series circuit with resistors of 3 kΩ, 5 kΩ, and 10 kΩ?

Back

Total resistance is 18 kΩ.

Front

How do you calculate total resistance in a series circuit?

Back

Add the resistance values of all components.

Front

What is the unit of electric current?

Back

Ampere (A).

Front

What is Ohm's Law?

Back

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

Front

What is a parallel circuit?

Back

A circuit with multiple paths for electricity to flow.

Front

How does current behave in a parallel circuit?

Back

Current is divided among the paths.

Front

What is the effect of adding more resistors in series?

Back

Total resistance increases.
