PRELIM-ELECTRICAL CIRCUITS(NS-IA)

electrolyte that ionise completely to form free mobile ions in the solution is known as

• strong electrolytes

• weak electrolytes

• cathode

• anode

conductors can allow electricity because of the presence of

• free ions

• free electrons

• free protons

• atoms

sea water is an example of

• bad conductor

• strong electrolyte

• weak electrolyte

• none of these

the method of purification of metals by using electricity is known as

• electroplating

• electrorefining

• electrometal

• none of these

What is Resistance?

• The flow of electrons
• Electric potential difference
• A battery
• The ability to reduce the flow of electrons

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light

The mathematical relationship among Voltage, Current, and Resistance

• Faraday's Law
• Tesla's Law
• Edison's Law
• Ohm's Law

Current times Resistance equals
 (I X R)

• Power
• Voltage
• Amperage
• Ohm

Negatively (-) charged particles around the nucleus of an atom

• atom

• electron

• proton

Law of electric charges states

• opposite charges attract and like charges repel

• opposite charges repel and like charges repel

• charges neither attract or repel
