R = V - I

I = V + R

V = I * R

V = R / I

V = R / I

I = V + R

R = V - I

V = I * R

Current increases when resistance increases.

Current remains constant when resistance increases.

Current decreases when resistance increases.

Current fluctuates randomly with resistance changes.

Static electricity is the buildup of electric charge on the surface of objects.

Static electricity is the energy produced by moving electrons in a circuit.

Static electricity is the phenomenon of electric charge moving through the air.

Static electricity is the flow of electric current through a conductor.

Static electricity is caused by the accumulation of electric charge due to electron transfer.

Static electricity occurs only in wet conditions.

Static electricity is generated by chemical reactions.

Static electricity is caused by magnetic fields.

Static electricity can be discharged by grounding or touching a conductive material.

By using a hairdryer to increase static charge

By applying water to the surface

By placing the object in a vacuum

The purpose of a fuse is to protect electrical circuits from overcurrent by breaking the circuit when the current exceeds a safe level.

To increase the voltage in the circuit.

To store electrical energy for later use.

To enhance the conductivity of the wires.

Insulated gloves, safety goggles, rubber-soled shoes, voltage tester.

Ear protection

Using water can enhance electrical conductivity.

Water helps cool down electrical devices.

It is important to avoid water when using electrical devices to prevent electric shock and short circuits.

Water is necessary for proper device operation.

To enhance the performance of electrical devices.

To increase the voltage in electrical circuits.

To serve as a power source for appliances.

To protect electrical circuits from overloads and faults.

Series circuits can have multiple paths, while parallel circuits have a single path.

Parallel circuits are always more efficient than series circuits regardless of the components used.

In series circuits, the voltage is divided equally among components, while in parallel circuits, it remains constant.

Series circuits have a single path for current, while parallel circuits have multiple paths.

Use metal tools for better conductivity

Work on live wires for faster repairs

Use insulated tools, avoid wet hands, check for damaged cords, and install GFCIs.

Ignore warning signs on electrical devices

Grounding is the disconnection of electrical systems from the earth.

Grounding refers to the insulation of electrical wires.

Grounding is the process of charging electrical systems.

Grounding is the connection of electrical systems to the earth for safety.

Continue using the device as normal.

Ignore the frayed cord and unplug it later.

Stop using the device and replace the frayed cord.

Wrap the frayed cord with tape.
