Electricity Flashcard

What is a series circuit?

Back

A series circuit is a type of electrical circuit where the current follows a single path. If one component fails, the entire circuit stops working.

What happens in a series circuit if one bulb goes out?

Back

If one bulb goes out in a series circuit, all the bulbs go out because the current cannot flow through the circuit.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the current can follow multiple paths. If one component fails, the other components can still function.

What happens in a parallel circuit if one bulb goes out?

Back

If one bulb goes out in a parallel circuit, the other bulbs remain lit because the current can still flow through the other paths.

How do you calculate resistance using Ohm's Law?

Back

Resistance (R) can be calculated using Ohm's Law: R = V/I, where V is voltage and I is current.

Front

What is the resistance in a circuit with 22 volts and 11 amps?

Back

The resistance is 2 ohms (R = 22V / 11A).

Front

What is the current in a circuit with 12 volts and 4 ohms?

Back

The current is 3 amps (I = V/R = 12V / 4Ω).

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V).

Front

What is current?

Back

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

Front

What is resistance?

Back

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