Which current is harmful AC or DC?

Answer:

Both AC and DC can be harmful, but the severity of harm depends on various factors like voltage, current, and duration of exposure.

Reasoning:

he harmfulness of a current depends on factors such as voltage, current intensity, and duration of exposure. Both AC (alternating current) and DC (direct current) can be harmful under certain conditions. The human body’s resistance, measured in ohms, determines the impact of electric current.

AC can be particularly dangerous because it periodically changes direction, potentially affecting the heart’s rhythm. However, DC can cause muscle contractions and burns, especially at higher voltages. The severity of harm is not solely based on the type of current but on the specific circumstances.

FAQs:

Q: Is AC or DC more dangerous?

A: Both can be dangerous; severity depends on factors like voltage and current intensity.

Q: Can low voltage DC be harmful?

A: Yes, even low voltage DC can be harmful if it reaches certain levels.

Q: How does AC affect the body?

A: AC can disrupt the heart’s rhythm, making it potentially more dangerous than DC.

Q: Can DC cause burns?

A: Yes, especially at higher voltages, DC can cause burns and muscle contractions.

Q: Why is AC considered more dangerous?

A: AC’s ability to affect the heart’s rhythm makes it potentially more dangerous, especially at higher voltages.

Q: What factors determine the harm caused by electric current?

A: Voltage, current intensity, and duration of exposure are key factors.

Q: Are there safety measures to reduce harm from electric current?

A: Yes, using proper insulation, circuit protection, and safety equipment can minimize risks.

Q: Can rubber gloves protect against electric shock?

A: Rubber gloves can provide insulation but may not be sufficient protection against high voltages.

Q: Does water increase the risk of electric shock?

A: Yes, water can conduct electricity and increase the risk of electric shock.

Q: Can electric shocks lead to long-term health issues?

A: Severe electric shocks can cause long-term health issues, including nerve damage and organ failure.
