Domestic uses and safety

What is alternating current (AC)?

Current that reverses direction

Match the feature with the correct type of current:

Current reverses direction ↔ AC

Current flows in one direction ↔ DC

What are common uses of DC?

Batteries, small electronics

What are common uses of AC?

Household power, large appliances

What is the voltage behavior of DC?

Constant

What are common uses of DC?

Batteries, small electronics

Match the waveform with its description:

AC Waveform ↔ Sinusoidal, reverses periodically

DC Waveform ↔ Constant voltage, flows one direction

Match the advantage of AC power transmission with its explanation:

Efficient Voltage Transformation ↔ Transformers easily step up and down voltage for long-distance transmission.

Reduced Energy Loss ↔ High voltage reduces current, minimizing heat and power loss.

Long-Distance Transmission ↔ Cables can transmit electricity efficiently over vast distances.

Match the advantage of DC with its explanation:

Reliability and Stability ↔ Provides a constant voltage, crucial for sensitive electronics.

Efficient for Low-Voltage Applications ↔ Directly usable in electronic devices without conversion.

Simplified Design ↔ Often has simpler designs, especially in electronic devices.

Battery Compatibility ↔ Directly compatible with batteries, ideal for portable and backup power.
