What is an electrical circuit?

• A type of electrical appliance used for cooking.

• A series of batteries connected in parallel.

• An electrical circuit is a closed loop that allows electric current to flow.

• A device that converts electrical energy into mechanical energy.

Explain Ohm's Law in your own words.

• Ohm's Law states that current is independent of voltage and resistance.

• Ohm's Law only applies to alternating current circuits.

• Ohm's Law describes the relationship between voltage, current, and resistance in an electrical circuit.

• Ohm's Law defines the power output of a circuit without considering resistance.

Name three common electrical devices.

• Television, Refrigerator, Microwave Oven

• Washing Machine

• Air Conditioner

• Toaster

How do you measure voltage in a circuit?

• Use an ammeter to measure voltage directly.

• Connect a voltmeter in parallel with the circuit component.

• Measure voltage by checking the current flow in the circuit.

• Connect a voltmeter in series with the circuit component.

What is the importance of safety in electrical work?

• Safety in electrical work is essential to prevent accidents and ensure the well-being of workers.

• Safety protocols are optional in electrical jobs.

• Electrical work does not require any safety measures.

• Safety is only necessary for high-voltage work.

What are the components of a simple electrical circuit?

• Battery, switch, diode

• Transformer, resistor, capacitor

• Generator, fuse, relay

• Power source, load, conductive path

How does resistance affect current flow?

• Resistance only affects voltage, not current.

• Resistance increases current flow.

• Resistance decreases current flow.

• Resistance has no effect on current flow.

What tools are used to measure electrical current?

• Wattmeters

• Ohmmeters

• Ammeters

• Voltmeters

Describe a safe practice when working with electricity.

• Ignore any frayed wires or damaged cords.

• Stand on a metal surface while working.

• Use wet hands to test electrical devices.

• Keep your hands dry and stand on a non-conductive surface.

What is the difference between AC and DC voltage?

• AC voltage is always higher than DC voltage.

• DC voltage alternates direction; AC voltage flows in one direction.

• AC voltage is used in batteries, while DC voltage is used in power lines.

• AC voltage alternates direction; DC voltage flows in one direction.
