Understanding Electric Shocks and Safety

What is the analogy used to explain voltage in an electrical circuit?

• Friction in a pipe

• Water pressure in a pipe

• Volume of water in a tank

• Speed of water flow

According to Ohm's Law, what is the relationship between voltage, current, and resistance?

• Voltage equals current times resistance

• Voltage equals resistance minus current

• Voltage equals current divided by resistance

• Voltage equals resistance divided by current

What is the primary factor that determines the severity of an electric shock?

• Voltage

• Current

• Frequency

• Duration

Why is immediate medical attention crucial in cases of severe electric shock?

• To lower voltage

• To reduce pain

• To restart the heart

• To prevent burns

What combination of factors contributes to the lethality of an electric shock?

• Voltage and resistance

• Current, frequency, and resistance

• Voltage, current, frequency, and duration

• Current and resistance

Why don't birds get electrocuted when sitting on power lines?

• They have high resistance

• There is no potential difference

• They are grounded

• They are insulated

How does wet skin affect the severity of an electric shock?

• Decreases resistance, increasing shock

• Increases voltage, reducing shock

• Has no effect on resistance

• Increases resistance, reducing shock

What is the resistance between the ears compared to hand to foot?

• Equal resistance

• Lower resistance between ears

• Higher resistance between ears

• No resistance between ears

What is the resistance of dry skin compared to wet skin?

• Equal resistance

• Lower resistance for dry skin

• Higher resistance for dry skin

• No resistance for dry skin

What is the best way to avoid electric shocks?

• Stay grounded

• Wear rubber gloves

• Avoid direct contact with conductors

• Use low voltage devices
